摘要：

A method is presented for solving the Boltzmann equation in layered systems without the relaxation-time approximation. The solution is compared with that obtained using the relaxation-time approximation for free-electron solids in the presence of boundaries. For the cases studied, most of the differences can be minimized by using the transport relaxation time. For nonfree electron materials it is expected that the differences will be more complex.
