Metrics for success in these applications have been tied to improved performance, reduced costs and enabling of new approaches rather than solely the smaller size scale of the new devices. This talk will briefly touch on some of the new devices and microsystems that are being developed at Sandia, such as devices for seismic monitoring, neural probes, components of an artificial retina, ultra-fast shock sensors, front-end CMOS integrated silicon nanowires and an atomic magnetometer. Another very exciting project, which at first look would not benefit from microsystems approaches, is photovoltaics. We have been developing a new manufacturing approach based on microsystems fabrication techniques which leverages the strengths of crystalline silicon devices and has the potential to lower costs below what is possible with standard crystalline silicon or thin film manufacturing techniques while enabling new form factors and deployment options. And, there will be plenty of time available after the seminar to talk about gliders and soaring.

Message-ID: <4AF9F351.8060201@stanford.edu> Greetings labmembers -- Just a reminder that the annual lab shutdown starts in Wednesday, Dec. 16, at 7 am and is accompanied by the Annual Lab Cleanup. Starting then, any personal items in the cleanroom not inside a storage bin will be removed from the lab. So save yourself the New Year ritual of sifting through dozens of boxes of stuff to find your wafers or notebook -- start collecting your personal items now! Speaking of items in the lab, some of the WIP racks are piled up higher than is considered safe. Please remove any items that are not being actively processed -- or staff will begin removing them, starting with unlabeled or undated/aged items. We won't wait for the shutdown to start cleaning up the WIP racks. Remember, WIP stands for "Work in Progress" not "Work in Permanence". Finally, make sure to label storage containers kept in the CAD room (151). Storage bins must be transparent and labeled with an active Coral ID and current date. Unlabeled, undated, and boxes older than one year are subject to removal.

Today a silicon chip the size of a fingernail contains over one billion transistors and has the computing power that only a decade ago would take up an entire room of servers. Silicon photonics based mainly upon silicon on insulator (SOI) has recently attracted a great deal of attention since it offers an opportunity for low cost optoelectronic solutions for applications ranging from telecommunications down to chip-to-chip interconnects as well as possible applications in emerging areas such as optical sensing and biomedical applications. Recent advances and research breakthroughs in silicon photonic device performance over last few years have shown that silicon can be considered as a material onto which one can build future optical devices. While significant efforts are needed to improve device performance and to "commercialize" these technologies, progress is moving at a rapid rate. If successful, silicon photonics may similarly come to dominate the optical communications as it has the electronics industry. This keynote will provide overview of silicon photonics research at Intel Corporation, describe some of the recent advances in device performance and discuss the key building blocks needed for "siliconizing" photonics. In addition the presentation will provide an overview and discussion on potential applications and future opportunities for enabling "photonics" in and around the PC and platform.

Pizza will be served. Tuning the shape of Semiconductor Nanowires for Advanced Photovoltaics *Jia Zhu* Department of Electrical Engineering Cui Group *Tuning the shape of nanostructures can have a strong effect on photon management and charge carrier collection for photovoltaics. Here we demonstrate two examples of nanowire shape designing: nanocones and branched nanowires.* *Compared to uniform diameter nanowires, nanocones have been shown for absorbing light with much reduced reflection due to near perfect impedance match. One step further, we demonstrate a new concept of nanodome solar cells, with nanocone arrays as the center piece of this design. The nanodome solar cells will not only greatly reduce light reflection, but also efficiently couple light into propagating wave, which dramatically enhance light travelling path. This new design provides another approach to decouple the direction of light absorption and charge collection, but with much reduced surface area and material usage, compared to nanowire radial p-n junction structure.** Amorphous Si solar cell was used as a demonstration of concept. Nanodome solar cells can absorb 46% more sunlight than flat film devices with the same thickness. We demonstrate nanodome devices with a power efficiency of 5.9%, which is 25% higher than flat film one. This nanodome design can be applied to a variety of other solar cell technologies. * *PbSe nanocrystals have shown greatly enhanced multi exciton generation (MEG) effect, one important step toward third generation solar cells. However, it is difficult o extract generated carriers from nanocrystals without good transport pathways. Three dimensional branched nanowire, with strong quantum confinement within two dimensions, and the connected third dimension as an efficient charge carrier pathway, can be ideal for enhanced MEG effect, light absorption, and carrier collection. We demonstrate successfully a large area growth of PbSe Hyperbranced and Chiral Branched Nanowires on a variety of substrates. More interestingly, Chiral Branched Nanowires reveal a new nanowire growth mechanism, dislocation driven growth, which can be applied to a variety of materials.* * * * * * * * * -------------- next part -------------- An HTML attachment was scrubbed...

Stanford University PhD Dissertation Defense Filip Crnogorac (filip at stanford.edu) Research Advisor: R. Fabian W. Pease Department of Electrical Engineering Time: Friday, November 20th, @ 1:00 pm (refreshments served at 12:45 pm) Location: Clark Center Auditorium (Basement, entrance across from Nexus) ABSTRACT The critical operation needed to achieve 3-dimensional integrated circuits is obtaining single-crystal, device-quality semiconductor material on upper circuit layers without damaging circuits below (400?C temperature limit). Simulation shows that microsecond pulse 532nm Nd:YAG laser can melt and crystallize amorphous Si or Ge layers without heating the circuit layers underneath. However, experimental results of unseeded (graphoepitaxy) and seeded (RMG) crystallization of Si and Ge indicate that much longer pulse lengths are required for high quality single crystal formation, rendering the approach not 3DIC compatible. A more straightforward approach is to directly attach high quality crystal islands for upper layer device fabrication. A variety of viable low-temperature (?400?C) bonding methods have been investigated: fusion bonding (SiO2-SiO2, Si-SiO2, Ge-SiO2), thermo- compressive bonding (Cu-Cu, Ti-Ti), as well as AlGe eutectic bonding. The unique advantages of AlGe technique for 3DICs are reported for the first time. They include superior bond strength, low void formation, no roughness requirement, use of thin films and CMOS friendly materials. Finally, we present a full 3DIC compatible process of obtaining single crystal Si or Ge islands for upper layer device fabrication via SmartCut(TM) and CMP finish. ------------------------------------------------------------------ From karthikv at stanford.edu Mon Nov 16 13:29:37 2009 From: karthikv at stanford.edu (Karthik Vijayraghavan) Date: Mon, 16 Nov 2009 13:29:37 -0800 Subject: TODAY: Special Seminar - MEMS at DARPA - Prof. Tom Kenny 4:00pm Allen 101X In-Reply-To: References: Message-ID: Special Seminar Where: ?Allen 101X When: ?4 PM on Monday November 16th MEMS at DARPA.

Pizza will be served. *Lateral Fusion of Lipid Membranes to Nanoscale Functionalized Posts* The ability to specifically and non-destructively incorporate inorganic structures into or through biological membranes is essential to realizing full bio-inorganic integration. However, molecular delivery and interfaces to inorganic objects, such as patch-clamp pipettes, generally rely upon destructive membrane holes and serendipitous adhesion, rather than selective penetration and attachment to the bilayer. In fact, materials greater than a few nanometers have not been shown to penetrate lipid bilayers without disrupting the continuity of the membrane. I will discuss the development of nanofabricated probes that spontaneously insert into the hydrophobic membrane core by mimicking the hydrophobic banding of transmembrane proteins, forming a well-defined bio-inorganic lateral junction. These biomimetic ?stealth? probes consist of hydrophilic posts with 2-10 nm hydrophobic bands formed by molecular self-assembly, and are easily fabricated onto a variety of substrates including silicon wafers, nanoparticles, and AFM tips. By fabricating this architecture onto AFM probes, we have directly measured the penetration behavior and adhesion force of different molecular functionalities within the bilayer. Following insertion, stealth probes remain anchored in the center of the bilayer, while purely hydrophilic probes have no preferred location. The strength of the stealth probe adhesion varies greatly between short and long chain alkane functionalizations, indicating that chain mobility, orientation, and hydrophobicity all contribute to stability within the bilayer. In addition, the consequences of geometric factors such as band thickness and the presence of multiple bands on interface stability have been established. By selectively choosing the desired properties of the hydrophobic band, it is possible to tune the failure tension of the interface from values comparable to that of pristine lipid vesicles to only a fraction of the strength. -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <4B06DE5E.2050405@stanford.edu> Greetings labmembers -- Four week warning. Remember, the annual lab shutdown starts in Wednesday, Dec. 16, at 7 am and is accompanied by the Annual Lab Cleanup. Starting then, any personal items in the cleanroom not inside a storage bin will be removed from the lab. So save yourself the New Year ritual of sifting through dozens of boxes of stuff to find your wafers or notebook -- start collecting your personal items now! Speaking of items in the lab, some of the WIP racks are piled up higher than is considered safe. Please remove any items that are not being actively processed -- or staff will begin removing them, starting with unlabeled or undated/aged items. We won't wait for the shutdown to start cleaning up the WIP racks. Remember, WIP stands for "Work in Progress" not "Work in Permanence". Finally, make sure to label storage containers kept in the CAD room (151). Storage bins must be transparent and labeled with an active Coral ID and current date. Unlabeled, undated, boxes and boxes older than one year WILL BE removed and dispositioned. Thanks for your attention -- Your SNF Staff -- Mary X.

There are 9 of them, mostly aimed down hallways. The primary use of these will be for education activities as outlined below. As education director of SNF, along with Maurice Stevens and Uli Thumser, I have developed remote access activities using webcameras in the past, mostly utilizing a single, Sony network camera, to transmit video images into classrooms from the cleanroom as part of NNIN/NSF education programs. I?ve also worked with Georgia Tech, another NNIN member, who has 14 webcams in their cleanroom (http://grover.mirc.gatech.edu/cameras/) which we have also utilized jointly for similar education activities, and which has been very successful. We now have decided to do similar education activities with fixed webcams in SNF. A common scenario is to give guided tours through the cleanroom, with Maurice or Uli for example going from room to room while talking by telephone to students in their classrooms while they watch and interact with Maurice through the image on a browser. We also will use them in conjunction with the Sony cam to do AFM and SEM demos, as well as other processing equipment. We also can use this to give lab tours to students in the Linvill conference room (101) rather than gown-up tours, which are very disruptive and difficult, or window tours, in which the students can not see much anyway. The webcam images are password protected, and would not be available to anyone except the students watching the remote activities on that day, and associated staff members such as myself. In certain situations, the webcams may also provide a benefit from a safety perspective. If alarms go off or we experience an earthquake, for example, senior staff would be able to do a quick check of cleanroom, even from home if necessary, in order to gain more information on what is occurring. Again, the images would not be available to anyone except a few SNF staff members through the password-protected interfaces. We will not be recording the images, except perhaps during education activities and only for those education purposes. We will not be using the webcams for surveillance, etc. We ask that you do not move our webcams. And do not think that you are being watched all the time - we will only be looking at the images during education activities, or for testing, or during safety-related situations. So in summary: - 9 webcams are now in the cleanroom - They will be used for education and safety-related situations only. - The images are password protected and will only be viewed during education activities, testing for those activities, and during safety-related situations, such as when alarms go off. - Please do not touch or move the webcams, or change their viewing direction. - If you have any questions, contact me, Mike Deal, SNF Education Director, 5-3607, mdeal at stanford.edu. -Thanks -Mike Deal, SNF From mtang at stanford.edu Wed Nov 25 16:57:10 2009 From: mtang at stanford.edu (Mary Tang) Date: Wed, 25 Nov 2009 16:57:10 -0800 Subject: Labmember Meeting on New Equipment: Wed. 12/1, 10-12 Message-ID: <4B0DD266.7040209@stanford.edu> Greetings all: Labmembers, PI's and research advisors are invited to an SNF Community meeting in which plans for new equipment acquisitions will be discussed. This meeting will be held on Wednesday, December 2, from 10 am- noon in the CISX Auditorium. As you may have heard, as part of the NNIN, SNF has received some funding to support new tools. Our proposal requested funding for tools on the SNF Faculty/Industrial AdCom wishlist. The tools that were funded are: ALD, Ebeam evaporator, sputter deposition, and PECVD. Over the past several months, a small group of SNF staff and labmembers have been meeting to explore the commercially available equipment options and solicit ideas from research groups. At this meeting, the New Equipment Group will present a summary of options, the trade-offs, and advantages/disadvantages of different approaches for each tool. Your participation and input are appreciated in helping to shape the final decisions. We ask interested research groups to make sure you are represented. Presentation slides will be posted on the wiki before the meeting and linked from the SNF home page. The agenda is as follows: 10-10:30 - ALD (J Provine) 10:30-11- Ebeam evaporator (Ed Myers) 11-11:30 - Sputter system (Ed Myers) 11:30-12 - PECVD (Jim McVittie) Feedback and discussion outside this meeting is also encouraged. Please feel free to contact any of us.

Message-ID: <4B10683F.5020409@stanford.edu> SNF Lab Members: Rostam asked me how to transfer files to/from memory sticks on the SunRays. I suspect that more than a few of you may be interested in that answer, so I will post it here. It turns out that it is quite simple .... but only if you know where to look for the files. In fact, we've added some features that should mount and show the files on your Memory Stick automatically. First, login to the SunRay that you want to use .... before your insert your memory stick. Second, insert your memory stick into one of the 4 USB slots in the back of the SunRay. This is actually the trickiest part as there are 4 closely spaced USB slots and two of them are in use with the keyboard and mouse. Depending on the size of the memory stick (the SunRays only have a USB 1.1 connection, I think ....) you will soon see a File Browser window open that contains the contents of your USB device. If you have a high-capacity memory stick, this may take a minute or two .... and the LED on your memory stick will likely be flashing as it figures out what is already on that device. In the top bar of the File Browser you will also see the name of the directory in which those files are mounted. That will be something like: /tmp/SUNWut/mnt/${user_name}/${memory_stick_name}. In other words, if your login name is johndoe and the name of your memory stick is MyFlashDrive, then all of your files will be visible in the directory /tmp/SUNWut/mnt/johndoe/MyFlashDrive. If you have not actually given your flash drive a name, it will appear in the directory named "noname" .... in other words /tmp/SUNWut/mnt/johndoe/noname. You can either use the GUI-based File Browser to copy files from your memory stick to some where in your home directory or can also copy files from your home directory to your memory stick. Of course, you can also open up a command window and use the Unix copy command to copy files to/from your memory stick. For example, to copy a file named MyFile.txt from your home directory to your memory stick named MyFlashDrive you could issue the command: cp ~/MyFile.txt /tmp/SUNWut/mnt/${user_name}/MyFlashDrive where, of course, ${user_name} is replaced by your login name. Alternatively, one way to copy a file named SomeOtherFile.txt from your flash drive named AnotherThumbDrive to your home directory would be to issue the command: cp /tmp/SUNWut/mnt/${user_name}/AnotherThumbDrive/SomeOtherFile.txt ~ If you are unfamiliar with Unix, the tilde character "~" is an alias for "my home directory". So, ~/SomeDirectory/SomeFile.txt is a way of naming the file SomeFile.txt that is in the directory named SomeDirectory in your home directory. In any event, I'm hopeful that you'll find this improved access to moving files onto or off of the SunRays with a USB. Note: when you are done with your USB memory stick, you simply have to remove it. Remember, if you have a big memory stick and it is quite full, it will take a while for this to open up on your desktop because the peak read rate of USB 1.1 is only 12 Mb/second (which is 1.5 MB/second) using the standard conventions of Mb = mega-bit and MB = mega-byte.
