|TITLE:||Nanodevices and Maxwell's Demon|
|DATE:||July 18, 2006|
It is common to differentiate between two ways of building a nanodevice: a top-down approach where we start from something big and chisel out what we want and a bottom-up approach where we start from small like atoms or molecules and assemble what we want. When it comes to describing current flow, the standard approach could be labeled conceptually as a "top-down" one that starts from large conductors and works its way down. In this talk I will present a "bottom-up" view of electrical conduction and use it to illustrate spintronic device concepts along with fundamental questions like wave-particle duality, reversibility and entanglement.
ABOUT THE SPEAKER
Prof. Supriyo Datta obtained his Bachelor's degree from IIT Kharagpur with Gold Medal from President of India in 1975. He did his MS and Ph D from University of Illinois, Urbana-Champaign, USA in 1977 and 1979 respectively. He is currently the Thomas Duncan Distinguished professor of Electrical and Computer Engineering and also Director of NASA Institute for Nanoelectronics and Computing, Purdue University, U.S.A.
He has contributed in different fields of research, from ultrasonics to spin electronics, molecular electronics and nanoscale device physics. A major part of Datta's work was to develop esoteric quantum transport formalism (non equilibrium Green's function) in to a powerful practical tool that can be used to model nanoelectronic devices. His pioneering work in spintronics has been widely referred to in the literature as Datta-Das transistor.
Prof. Datta received Cledo Brunetti Award in 2002 from IEEE for the outstanding and innovative simulation of nanoscale electronic devices and Herbert Newby McCoy award in 2006 for the most important contribution to science.
