Catalog Description:
The modern smartphone is enabled by a billion-plus nano-transistors, each having an active region that is barely a few hundred atoms long. Interestingly the same amazing technology has also led to a deeper understanding of the nature of current flow on an atomic scale. The aim of this course is to make the fundamentals of nanoelectronics accessible to anyone in any branch of science or engineering, assuming very little background beyond linear algebra and differential equations, although we will be discussing advanced concepts in non-equilibrium statistical mechanics that should be of interest even to specialists. We first introduce a new perspective connecting the quantized conductance of short ballistic conductors to the familiar Ohm???s law of long diffusive conductors, along with a brief description of the modern nano-transistor. We then address fundamental conceptual issues related to the meaning of resistance on an atomic scale, the interconversion of electricity and heat, the second law of thermodynamics and the fuel value of information. Finally we introduce the concepts of quantum transport as applied to modern nanoscale electronic devices.

Supplementary Information:
Note: This course is currently running as three 5-week modules: ECE 59500: Fundamentals of Current Flow, ECE 59500: Introduction to Quantum Transport and ECE 59500 Boltzmann Law: Physics to Machine Learning. BSEE students must take all three for them to count toward an Advanced Selective course.
