摘要：
A rigorous quantum treatment of real-space transfer for electrons from a quantum well is developed within the density matrix and Wigner functions formalisms. A continuous electron dynamically evolution (not an abrupt collision) corresponding to a phonon absorption is described. From the evaluation of the lowest-order correction to the unperturbed density matrix, the spatial and momentum distributions can be evaluated. The Wigner and Husimi functions are also shown for the physical situations of interest.
