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