Abstract
A theoretical calculation of impact ionization using quantum transport is pre-sented here. An atomistic matrix Hamiltonian in real space, capable of capturing complex mass tensors in heterostructures, is combined with Non-equilibrium Green’s functions using a self-consistent Born approximation for Coulomb interactions between electrons and holes.
