Graphene and Carbon Nanotube Electronics: Device Physics and Simulation
Mon, Apr 05, 2010 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
University Calendar
Jing Guo - University of FloridaAbstract: In recent years, significant progress has been achieved in graphene and carbon nanotube
(CNT) electronics. In a graphene or carbon nanotube, low bias transport can be nearly ballistic.
Deposition of high-ê gate insulators does not degrade the carrier mobility because of an absence of
dangling bonds. The conduction and valence bands are symmetric, which is advantageous for
complementary applications. The Excellent transport property promises high-speed transistor
applications. Carbon-based nanostructures are receiving much attention for possible device applications.
We have developed a self-consistent atomistic simulator for graphene and CNT field-effect transistors
(FETs) based on the non-equilibrium Green's function (NEGF) formalism, and applied it to understand
and explain experiments. The simulator provides an atomistic scale description for quantum transport in
the presence of inelastic scattering and electron-photon interaction. We show that CNTFET is capable of
delivering a near ballistic DC on-current even under high source-drain bias conditions. The radio
frequency (RF) characteristics of CNTFETs are simulated for understanding potential high-speed
transistor applications. On graphene electronics, we show that edge chemistry of graphene nanoribbons
(GNRs) provides promising opportunities to engineer the device properties. Device physics and design
options of GNR-based tunneling transistors are also examined by atomistic device simulations.Biography: Jing Guo received the Ph.D. degree in electrical engineering from Purdue University, West
Lafayette, IN, and subsequently joined University of Florida as an assistant professor in Aug. 2004. His
research interests focus on modeling and simulation of nanoscale devices with applications in electronics and
optoelectronics, in close collaboration with experimentalists. He has published over sixty peer-reviewed
journal papers on prestigious journals including Science, Nature, Phys. Rev. Lett., Nano Lett., Appl. Phys.
Lett., Nature Nanotechnology, and IEEE Transactions. He is a recipient of the National Science Foundation
(NSF) Faculty Early CAREER Award, and served in the technical program committee of International
Electron Device Meeting (IEDM) and Device Research Conference (DRC). He is the coauthor of the book,
"Nanoscale Transistors: Device Physics, Modeling, and Simulation" published by Springer.Location: Hughes Aircraft Electrical Engineering Center (EEB) - 248

... Building Collapse and Other Collapse-Related Stuff Speaker: Sherif El-Tawil,Professor, Civil and Environmental Engineering Department,University of Michigan, Ann Arbor, MIAbstract:
Simulating the response of a steel building to extreme loading, especially all the way up to collapse, is complicated by the need to account for a number of interlinked processes that take place along widely disparate length scales. At the micro-scale, micrometer sized voids in the steel matrix can nucleate and coalesce leading to the formation of a crack. At the macro-scale, the crack can grow forming a discontinuity (centimeters in length) that leads to a rapid change in member structural properties. At the structural-scale, i.e. in regions measured in meters, the damaged member can trigger instability in subassemblage response potentially leading to a chain of other interlinked micro-, macro- and structural-scale processes that ultimately stop when the building system reaches equilibrium or collapses into a debris pile. My talk will start off by describing my general research interest in multi-scale collapse modeling then focus on simulating progressive structural collapse and some of the engineering aspects that influence the collapse-resistance of steel buildings. Digressing from the main topic of the presentation, I will describe some tools that we have developed to visualize our simulation results in virtual and augmented reality environments with the purpose of assisting and training first response teams. The talk will conclude with a short discussion of emergency occupant egress from distressed buildings and our ongoing efforts to address this area.
