Abstract
The impact ionization rate and its orientation dependence in k space a re calculated for ZnS. The numerical results indicate a strong correla tion to the band structure. The use of a q-dependent screening functio n for the Coulomb-interaction between conduction and valence electrons is found to be essential. A simple fit formula is presented for easy calculation of the energy-dependent transition rate.
