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.
