Hot Carrier in Subpicosecond Photoconductive Experiments
Abstract
The goal of this program was the development and use of models of femtosecond photoconductive experiments as probes of hot carrier transport in semiconductors. Prototype experiments were being carried out in a companion effort directed by Dr. Gerald Mourou at the University of Rochester, Rochester, New York. The Arizona State University modeling effort was directed at several main components to the modeling of such experiments. One must first model the generation of electron-hole pairs inside a semiconductor as a result of the incidence of a femtosecond optical pulse. Then one must model the processes by which the resulting current transient is developed. Lastly, the conversion of the current transient into a voltage wave transmitted down a transmission line must be understood. It is this voltage wave that is directly measured in the experiments of interest. Successful models of all three components were developed.
