From sensing and modulation, to on-chip communication and light trapping in solar cells, new device applications and opportunities now motivate the need for a richer understanding of the optical properties of plasmonic structures and metamaterials over a broad range of frequencies. In this talk, I will first introduce a photonic band theory that rigorously models the broadband behavior of plasmonic nanostructures and metamaterials. The theory formulates plasmonic band structures as Hermitian eigenvalue equations, and offers an intuitive physical picture of modal material loss. An upper bound on the modal material loss rate is then derived, placing fundamental limits on device operation. Furthermore, I will present a perturbation theory that elucidates the effect of dielectric refractive index modulation and metallic plasma frequency variation in plasmonic nanostructures. Next, I will present a nanophotonic light trapping theory for solar cells and show that, using a nanophotonic design, one can exceed conventional limits on light trapping for all absorption regimes of the active material. The theory's insights are then applied to organic solar cells to design a dielectric light trapping structure that provides 10-15% photocurrent enhancement relative to an optimized planar organic solar cell. Finally, I will use the plasmonic band theory to probe the role of parasitic loss in the metal on achievable absorption enhancement factors in plasmonic light trapping schemes. -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: Department of Electrical Engineering University PhD Oral Examination Nanoelectromechanical Relays for Low Power Digital Systems Wm. Scott Lee Research Advisor: Professor Roger Howe Friday, February 15, 2013 @ 10AM (Refreshments @ 9:45AM) Location: Packard Building, Room 202 ABSTRACT Field programmable gate arrays (FPGAs) are flexible digital circuits capable of implementing arbitrary digital logic. This flexibility comes at a price: a digital function implemented on an FPGA requires more area and power while operating at a lower speed compared to the same function built on an application specific integrated circuit (ASIC). The overhead required to implement the programmable routing is directly responsible for much of the discrepancy. By replacing the FPGA pass transistors and SRAM programming cells with low leakage nanolectromechanical (NEM) relays, this overhead can be significantly reduced without a reduction in speed. The NEM relay consists of a released beam, a fixed gate electrode, and a fixed drain electrode. When the relay is out of contact, an air gap separates the beam and drain resulting in zero leakage. When the relay moves into contact, electrical current passes from the drain to the beam. In this work, we investigate NEM relays as potential FPGA routing elements. The NEM relays must meet certain metrics with respect to contact resistance, cycling, and hysteresis to obtain significant benefits for the FPGA. NEM relays are fabricated and characterized to determine if they meet these metrics. Design and fabrication techniques are developed to decrease the contact resistance and achieve better control of the hysteresis window. These techniques enable three regions of varying stiffness for the spring, the actuation electrode, and the contact. Contact materials such as titanium nitride, hafnium diboride, and ruthenium are also explored as a means of reaching these metrics. -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <51213B63.4050702@stanford.edu> SNF Lab Members: As you may recall, our equipment mailing lists are still using subscriptions of the form coral_name at snf.stanford.edu and relying on email forwarding to get messages directed to the proper address. We now believe that the great majority of you have completed your Badger conversion and equipment qualifications. As a result, it now seems to be a good time to convert all of our mailing lists so that they use your badger_name (which is an email address) as the address to which you are subscribed to our lists. Later today, I expect to run a script that will effect that conversion based on the existing Badger equipment qualifications. Then, the labmembers list will be populated on a nightly basis based on the list of subscribers to all other lists. Because Badger does not automatically subscribe you to mailing lists based on equipment qualifications, I will periodically re-run this script to add newly qualified members to appropriate lists. After I have run this conversion, I will send out a message to the "newly constituted" labmembers at snf.stanford.edu ... likely in the next couple of hours. If you do not receive this second message, you likely fell through the cracks. (Note: I realize that this is dangerously close to asking you "Please let me know if you don't receive this ..."). Note: we do have a mechanism for making sure that you are added to the labmembers at snf.stanford.edu list even if you are not qualified to use any piece of equipment. If you fall into this category, please send me email and ask me to add you to the "courtesy" list. So, in the next hour or two (it is now nearing 12:30 p.m. on Sunday, February 17) you should receive a second message posted to the new labmembers mailing list. If you receive that message, you don't have to do anything ... other than to know that you are subscribed to the labmembers mailing list under your Badger name. If you encounter any problems, please don't reply to the labmembers mailing list, but to me directly: shott at stanford.edu. Thanks for your cooperation, John p.s.

Balram Message-ID: <461755403.1020306.1361253709948.JavaMail.root@stanford.edu> Department of Electrical Engineering University PhD Dissertation Defense Nanoscale Transverse Fabry-Perot Resonators Krishna C. Balram Advisor: Prof. David A. B. Miller Monday February 25 th , 2013 @ 4:15 PM (Refreshments at 4 PM) Location: Spilker (formerly Nano bldg.), Room 232 (Map: http://campus-map. stanford.edu/index.cfm?ID=04- 040 ) ABSTRACT The ability to fabricate multiple resonant photodetectors, each with separately engineered wavelength sensitivity, in a single-step process has many potential applications. In this talk, we propose and demonstrate the use of nanoscale semiconductor fin structures surrounded by metal as efficient transverse Fabry-Perot resonators which allow one to efficiently excite in-plane resonances under surface-normal incidence. We show that these devices support strong absorption resonances that can be tuned by varying the width of the structure and use this effect to engineer devices for two potential application areas. In the first half of the talk, we show how we can engineer nanoscale planar multispectral image sensors based on silicon fins surrounded by metallic slits wherein the resonant wavelength of each pixel is determined by the width of the silicon fin. The same metallic structure is used for both light confinement and carrier extraction in a compact metal-semiconductor-metal (MSM) geometry. We experimentally study how close we can put two of these pixels together and how small we can make an individual pixel. We show that, in principle if the electrical properties of the devices are suitably controlled, one can engineer devices with pixel pitch down to 250 nm and pixel sizes ~ 500 nm x 500 nm. In the second half of the talk, we use this effect to enhance the indirect absorption in germanium and engineer CMOS-compatible germanium photodetectors with high responsivity across the telecommunications bands (both C & L-bands). Finally, we show that this effect can be used to engineer novel resonant waveguide couplers that can be used to couple light efficiently from free space to both dielectric and plasmonic slot waveguides with slot widths on the order of 50 nm. -------------- next part -------------- An HTML attachment was scrubbed...

Message-ID: <5126FA06.7080006@stanford.edu> SNF Lab Members and Allen building occupants: If you were in the area this evening, you know that the blue toxic gas alarms and the building fire alarm went off this evening at about 6:15 p.m. Palo Alto Fire and the Stanford Sheriff's department responded shortly thereafter. Jim Haydon was the first staff member on scene and I arrived shortly thereafter. Mary Calarrudo had already provided PAFD with her card key to make sure that they had access to appropriate areas. Hydrogen was detected by many of the hydrogen detectors located throughout the building. The cause of those alarms was due to hydrogen that is released as a normal part of the tank fill operation when the Air Products tank truck fills our tank. When they have filled our tank, there is residual hydrogen in the line between the Air Products tanker and our tank. This hydrogen is carefully released into the atmosphere. Unfortunately, when atmospheric conditions (primarily wind velocity and wind direction) are just right, that hydrogen can get "sucked into" the building air handling systems where it is then blown across the hydrogen detectors in the lab and in the labs in the annex. Our hydrogen detectors are set to alarm if they detect 400 ppm (parts per million) hydrogen in the air because we want to be aware of leaks as soon as possible. The peak level of hydrogen that was seen by these detectors this evening was approximately 500 ppm. None of you in the building were at risk under those conditions: the lower flammability limit of hydrogen in air is 4% (800 times greater concentration that we observed). At this point, all systems have been restored to full service. We will be working with appropriate people and groups to see if we can avoid this problem in the future. We apologize for any inconvenience or anxiety that this event caused. Please let me know if you have any further questions related to this event. I would be happy to discuss this with you.

We show that our method may indeed be capable of designing any linear nanophotonic device by demonstrating designed structures which * are fully three-dimensional, * are multi-modal, * exhibit novel functionality, * have very compact footprints, * exhibit high efficiency, and * are manufacturable. Critically, we show that our method does not require the user to be a nanophotonic expert or to perform any manual tuning. Instead, we are able to design devices solely based on the user's desired performance specification for the device.
