From darve at stanford.edu Mon Dec 3 10:02:19 2007 From: darve at stanford.edu (Eric Darve) Date: Mon, 3 Dec 2007 10:02:19 -0800 Subject: Seminar by K. Stokbro on nanoscale electronic devices 12/13 4:15PM Message-ID: <3ae0cc8e0712031002h76c8b16eha92fe7d6cf2dcb4b@mail.gmail.com> Hi, Kurt Stokbro will be giving a talk in EDUC128 at 4:15PM on modeling the electronic properties of nanoscale devices. Refreshments will be served at 4PM. Dr Kurt Stokbro, born 1965, is an educated physicist, co founder and CEO of Atomistix Inc. He has previously held positions at the Technical University of Denmark and Copenhagen University, where he has coordinated a number of EU and Danish-funded R&D projects. Dr. Stokbro has published more than 50 papers and review articles in international journals, held a large number of lectures as invited speaker and has organized 3 international conferences in nanoscience. Dr Stokbro is external adviser to the International Research Committee(IRC) in Nanotechnology at University of Cambridge, the Center for Computational Atomic-scale Materials Design(CAMD) at the Technical University of Denmark and member of the modeling sector of the International Technology Roadmap for Semiconductors (ITRS). The scheme for ab initio calculations of quantum transport, developed by Dr. Stokbro and co-workers, has become the de facto standard for electron transport calculations and has laid the foundation for Atomistix A/S. Kurt is staying at Stanford until the end of the quarter so feel free to email him if you wish to meet with him. Where: EDUC128 When: 12/13 4:15PM-5:30PM Speaker: Kurt Stokbro Department of Computer Science, University of Copenhagen (DIKU) Universitetsparken 1, 2100 Copenhagen, Denmark Title: First principles modeling of the electrical properties of nanoscale devices Abstract: The minimum feature size of electronic devices is approaching the atomic scale and at this scale the quantum nature of electrons start to alter the device behavior in new ways. The new effects requires modifications of the device geometries and introduction of new device materials and I will in my introduction give a brief overview of some of the most recent developments in the semiconductor industry and what can be anticipated in the future. For successful introduction of the new technologies it is important with reliable modeling tools that allow for testing and optimizing the new materials and device geometries. However, many of the atomic-scale effects are not included in the current modeling tools used in the semi-conductor industry and as member of the International Technology Roadmap for the Semiconductors (ITRS - http://www.itrs.net/) I have been involved in putting forward a list of modeling challenges that must be addressed in order to model semiconductor devices below the 32 nm node. In this talk I will discuss my research in the field of quantum transport based on Density Functional Theory within the Non Equilibrium Greens Function formalism, NEGF-DFT and how this methodology can be used to address the challenges in the ITRS roadmap. The methodology has so far been applied to new emerging device geometries based on carbon nanotubes, 1-D graphene sheets, molecules, atomic wires, or magnetic materials and I will present results from these studies. These emerging devices are still rather exotic and are expected to enter the market more that 10 years out in the future. In order make the tools able to model more traditional semiconductor device geometries and thereby address more near time challenges in the semiconductor industry, it is necessary to develop new more efficient and highly parallel algorithms that can treat systems with many thousand atoms. In the Nanopar ( nanopar.wordpress.com/) project at Copenhagen University we are looking into new algorithms that give O(N) scaling of computational time with system size and which speed-up state of the art algorithms by orders of magnitude. I will present the most recent results in this project and discuss our future path towards enabling large scale device simulations comprising millions of atoms.

ORAL EXAMINATION PHOTOELECTRONIC ANALOG TO DIGITAL CONVERSION RAFAEL ALDANA Department of Electrical Engineering Stanford University CIS Extension Auditorium Thursday, December 6th 2007 10:00- 11:00 am Refreshments: 9:45 am Abstract: Miniaturization has primarily benefited digital, rather than analog, electronics both in terms of speed and cost. This has led to an increasing need to convert analog signals to digital at high speed. Historically this Analog to Digital Converters and other information encoding systems were based in electron beam deflection, in the form of oscilloscopes and cathode ray tubes; but inherent limitations due to price, size and versatility made them, if not obsolete, at least far less common than in previous ages. Recent advances in microfabrication seem able to make these systems attain performances comparable, if not better than those of their replacements. In this work we present one of such a miniaturized system, a Niquyst rate analog to digital converter, and establish the fundamental and practical limits of its performance. For that purpose we built an electron beam based analog to digital converter with sampling rate of 3GHz and 5 bits of resolution. In it, a pulsed electron beam is swept through a set of deflection plates to which the analog signal is fed; the lateral deflection imparted by the plates is proportional to the signal to be sampled. The electron bunches travel through a field free region and hit a Metal-Semiconductor-Metal detector column at a position that determines the digital code. The system has two characteristics that make it a great candidate for fast ADCs: the use of a pulsed electron beam, resulting from a low jitter mode-locked laser illuminating a photocathode; and the use of spatial quantization. The main advantage of the proposed system is its versatility, given by the use of multiple electron beams generated using a photocathode illuminated by laser pulses staggered in time, the deflection of all multiple beams with a single set of traveling wave plates, and the use of detector columns with variable detector configurations.

Staff will be around for the remainder of the week and may be present during the holidays. Now, here's the serious part. NO LABMEMBERS ALLOWED IN THE LAB starting Wednesday morning. There will be Facilities and Building work as well as work done on equipment and chemical benches. Exhaust may be reduced or nonexistent. Because of these safety concerns, any labmember entering or using the lab unescorted by SNF or Facilities staff during lab shutdown will lose his/her lab privileges. The lab will reopen for business at 7 am on Friday, January 4. On Thursday, staff will be on the job, restarting equipment. We expect most equipment to be functional although perhaps not fully tested on Friday morning. Please note that all personal items in the lab which are found outside of personal storage bins will be removed from the lab. These and any other unclaimed items will be kept in the Lost-and-Found. If there are any questions about the upcoming shutdown, please ask your favorite staff member. Happy holidays! Your SNF Staff -- Mary X.

This presentation discusses some of the recent work at the University of Southampton in the area of AC electrokinetics, electrowetting and microimpedance spectroscopy. Dielectrophoresis (DEP) is the movement and manipulation of particles by the application of non-uniform electric fields. The DEP force spectrum is unique to a given particle type, providing a powerful method for separation of particles. DEP is also a non-contact method, making it ideal for the manipulation, trapping and separation of biological particles such as cell, bacteria and viruses. The implementation of DEP in single cell manipulation and measurement techniques for a microflow cytometer is discussed. The development of a scalable DEP-well array technology for the trapping, analysis and measurement of single cells is presented, as well as the continuous flow-through separation of nano-particles is discussed. The development of a microflow cytometer, which uses impedance and laser spectroscopy for the analysis of single cells and particles, is also discussed. The advantages of impedance spectroscopy in general and single cell spectroscopy in particular are examined. The application of the cytometer for the analysis of blood cell and marine algae samples are considered. Finally the use of AC electric fields for the manipulation and control of fluids is covered. The use of carbonised SU8 structures for high density AC electroosmotic micropumps is explored. The development of ultra low voltage (5V) electrowetting devices for microdroplet manipulation is discussed, along with the application of the technique for the construction of artificial lipid bilayer structures. This extremely useful technique has applications in the field of bionanotechnology in the measurement and characterisation of membrane proteins and ion channels. The application of this method is demonstrated in the measurement of simple channel proteins e.g. a-hemolysin. -------------- next part -------------- An HTML attachment was scrubbed...
