Nano materials seminar on Monday, March 18
by Anthrop, Heather L 15 Mar '13

15 Mar '13

Monday, March 18, 2013 3:30 p.m. 2-425 Lilly (3:15 pm for pre-visiting, coffee, refreshments) Some Investigations of Metal Oxide Nanomaterials and Terrestrial Organisms Patricia Holden University of California, Santa Barbara [cid:image002.jpg@01CE2181.C896B1E0]Manufactured nanomaterials (MNMs) are increasingly produced and used, and therefore are entering the environment. Still, little is known about potential environmental effects and therefore how to design MNMs to safeguard the environment. Soils are expected to be accumulators of MNMs, mainly in the U.S. from biosolids land disposal practices. While some MNMs may not be bioavailable in soil, other MNM chemistries may result in soil microbial and plant exposure. We have been studying bacterial population and community level effects of some common metal oxide MNMs. Our collaborators have studied plant population effects with similar materials. Results from both types of experiments will be discussed. Then, a greenhouse experiment with soybean in organic farm soil will be presented, where similar MNMs were examined for their effects on plants, microbes, and plant-microbe interactions in a more agriculturally-realistic context. The results suggest potential effects of these MNMs long term, if there is buildup in soil. A broader discussion is then suggested about contexts, and controls, in conducting such experiments. The work presented is representative of results in the University of California, Center for Environmental Implications of Nanotechnology, within which Holden is a member and leader of Theme 4 "Terrestrial Ecosystem Impacts".

Date Change: Dr. Jan Mol's Seminar "Acceptor Based Qubits in Silicon"
by Buckles, Amanda L 12 Mar '13

12 Mar '13

Please be aware, this seminar has been moved to Thursday, March 14, 2013. Acceptor based qubits in silicon Thursday, March 14, 2013 11:00AM Burton Morgan Building, Room 129 Dr. Jan Mol Centre for Quantum Computation and Communication Technology University of New South Wales, Sydney, Australia Systems with spin-orbit interaction have significant potential for solid-state quantum computation. Coupling between the orbital angular momentum and the spin in the valence band of silicon opens the possibility for rapid all-electrical manipulation of an acceptor-bound spin-orbit state, while selection rules can provide a qubit basis that is protected from decoherence by time-reversal symmetry. Building on the seminal work of Kane, I will present a design for an acceptor-based quantum computer where the transitions between the working levels of the qubit can be switched on and off by manipulating the acceptor wave function. The crucial parameter here is the interface-induced energy splitting between the two Kramers doublets that make up the ground state of the undisturbed acceptor wave function. Based on fully atomistic tight binding simulations and low-temperature scanning tunnelling spectroscopy interface-split Kramers doublets of individual boron acceptors near a silicon surface are visualised and identified. The electron temperature in the sample is used as a reference to directly determine the energy splitting between the Kramers doublets as a function of acceptor depth which is found to be in good agreement with calculations. Finally, the observed energy splitting of ~4 meV effectively protects acceptor-based qubit from decoherence. About the Speaker: After graduating with a Master's Degree in Applied Physics at the Delft University of Technology in the Netherlands I obtained my PhD Degree in Delft in 2012 studying Single Atom Electronics in the group of Prof. dr. Sven Rogge. During my time as a PhD student I moved to Sydney, Australia where I am currently working as a Postdoctoral Fellow at the Centre for Quantum Computation and Communication Technology at the University of New South Wales. My research focusses on studying single dopant atoms in silicon using Scanning Tunneling Spectroscopy with the emphasis on using dopants as building blocks for quantum computation.

Friday, March 15th OSA - Purdue Chapter Meeting Birck 1001 at 11:00 am ***Special Notice*** Attention all cleanroom users: The hard drive on the ECE 557 microscope computer is filling up with files from users that are not in ECE 557. If you have files on this computer, please remove them prior to March 18th. All non-ECE 557 files will be removed on March 19th to make room for class project files. Thank you for your attention to this. Jun Park, TA Thank you, Heather Anthrop Birck Nanotechnology Center Purdue University 1205 West State Street West Lafayette, IN 47907 (765) 494-7053

07 Mar '13

Everyone, We will be trying to get the new card reader on line today. We will have a short (hopefully) 10-15 minute time when the doors will lock. If you need in somewhere right away and the door is locked, please call me right away at 496-1173 or 494-4491. Thank you, Mary Jo Totten Birck Nanotechnology Center Discovery Park/Purdue University 1205 West State Street West Lafayette, IN 47907-2057 (765) 496-1173 Your imagination is your preview of life's coming attractions" -Albert Einstein

Prof. Stephen Campbell Seminar - today at 11am in BRK 2001
by Turner, Jaime J 07 Mar '13

07 Mar '13

Prof. Stephen A Campbell - Carbon-Based Nanoswitch Logic March 7 @ 11:00 AM - 12:00 PM - Birck Room 2001 Abstract:The process of shrinking semiconductor devices employed for fifty years has almost reached its end. Fundamental limitations of the field effect device prevent much additional reduction in the supply voltage. This leads to unavoidable off-state leakage and very high operating power, an intolerable situation, especially for mobile applications. This is leading to radical changes in the roadmap, forecasting separate technologies for high performance, low operating power, and low standby power applications. Scaling will not provide significant performance improvements for the latter two. While research into novel devices is underway, progress has been much slower than one might like. This talk discusses a rather surprising possibility: the use of carbon-based materials such as carbon nanotubes and grapheneto make nanomechanical switches with at least an order of magnitude lower power dissipation than the low power CMOS options and performance between the various CMOS technologies. It is the unusual properties of these materials that make possible such high performance, very low power digital logic. The technological barriers needed to realize such a technology will be discussed along with work that has been done to demonstrate possible solutions. The potential implications of such a technology will be discussed. Bio: Stephen A. Campbell received a B.A. in physics from St. Thomas University and an M.S. and PhD in physics from Northwestern University in Evanston Illinois in 1977 and 1981, respectively. After a brief stint at Unisys where he worked on CMOS, he joined the University of Minnesota in Minneapolis Minnesota in 1986. He is on the faculty of the Department of Electrical and Computer Engineering and is directs the NanoFabricationCenter (www.nfc.umn.edu<http://www.nfc.umn.edu/>), one of the NNIN nodes. He has about 200 refereed publications. His textbook, Fabrication Engineering at the Micro- and NanoscaleNew York: Oxford University Press, 1996, 2001, 2006, 2013 has been used in over 80 US schools as well as institutions in Europe and Asia. It has been translated into several languages. His work in the area of silicon process technology ultimately led to fundamental changes in the way that CMOS transistors are manufactured. More recently Professor Campbell has worked on carbon-based nanoelectromechanical devices (NEMS), silicon quantum dots, and thin film solar cells. Professor Campbell is a fellow of the IEEE, holds the Sanford P. and Lenore Edgerton BordeauChair in Electrical and Computer Engineering and is a Distinguished Professor in the University's College of Science and Jaime Turner Birck Nanotechnology Center Purdue University 1205 West State STreet West Lafayette, IN 47907-2057 (765) 494-3509 jjturner(a)purdue.edu
