Abstract
A quantum BGK transport model is proposed. The collision term is modelled as a perturbation of the classical one. The quantum correction to the h(2) order is given as a relaxation term involving the equilibrium Wigner function in a thermal bath of phonons in the case of an arbitrary energy band. The application to the case of the Kane dispersion relation is shown.File in questo prodotto:
