This paper is intended to study, in a quantum scheme, the effects of impurity scattering on transient transport properties of hot electrons. The theoretical approach, based on a perturbative solution of the Liouville-von Neumann equation, considers terms, not present in the semiclassical limit of the theory, which can be regarded as higher-order corrections to the Fermi golden rule and multiple collisions. The diagrammatic representation describing the electron-phonon interaction is extended to impurity scattering, and the Quantum Monte Carlo procedure, based on a random generation of such diagrams, is developed. In particular, interference between impurity scattering and phonon scattering is considered. The results of the quantum simulated experiment are compared with the classical ones and, at short times of the order of 100 fs, typical quantum effects are pointed out.
