| Title: Hot Electrons: A Myth or Reality? |
| Speaker: Professor Vijay K. Arora Wilkes University Wilkes-Barre, Pennsylvania |
| Abstract: A review of steady-state electronic transport in a high electric field is given. In particular, expressions for mobility and diffusion-coefficient degradation are obtained in the framework of asymmetric distribution function [1]. The concept of a hot electron and its temperature in a given context is discussed and simple analytical expressions extracted. These contextual definitions include: energy temperature, mobility temperature, Einstein-relation temperature both under ac and dc conditions, quantum temperature, and two-band intrinsic temperature. The dependence on the electric field is given in each case and the role of electric-field-induced quantum emission is delineated. [1] Vijay K.
