Abstract

A general investigation of the velocity autocorrelation function for high electric field transport in Si is presented. Calculations have been carried out using a Monte Carlo technique for calculating the transport parameters. Additionally, a generalized model for defining diffusion and mobility in terms of a transport equation is presented. A detailed Schockley model is used to evaluate these equations for the velocity autocorrelation function. It is found that phi '(t) initially relaxes exponentially, due to momentum relaxation, goes negative and displays a local minimum, then relaxes to zero at a slower rate due to energy relaxation.
