摘要：
Using quantum kinetic equations with memory we calculate the time-dependent distribution function of an electron gas injected suddenly in the conduction band of a wide-band-gap insulator. A comparison is made with the semiclassical Boltzmann equation approach. We show that due to the large electron-phonon coupling occurring in such materials a quantum approach is needed.
