Abstract
Using quantum kinetic equations with memory we calculate the time-depe ndent distribution function of an electron gas injected suddenly in th e conduction band of a wide-band-gap insulator. A comparison is made w ith the semiclassical Boltzmann equation approach. We show that due to the large electron-phonon coupling occurring in such materials a quan tum approach is needed.
