Abstract

The role of the finite collision duration in high electric fields is examined for its effect on the scattering rate relevant in many submicron and nanoscale semiconductor devices. Starting from a general non-linear quantum transport equation, an approximate high field quantum kinetic equation is derived, which can be viewed as the first step towards a quantum Boltzmann equation. Based on this equation, the high field scattering rate of electrons is calculated for GaAs in the case of optical phonon scattering at room temperature.
