摘要：

A cost effective solution of the Boltzmann equation can be obtained by a spherical harmonics expansion. The Letter introduces improved boundary conditions which account for the fact that the electrons absorbed by a contact may be strongly heated. It is shown that simulations with the new boundary conditions lead to improved results compared to the equilibrium boundary conditions used previously.
