Abstract :
In this paper, the influence of coherent and incoherent boundary conditions for quantum transport through silicon nanowires is studied. An iteration scheme to compute an approximate self-energy in the contacts is proposed. The focus lies on the impact on the self-consistent electrostatics and the current computation. In addition, the scaling behavior with increasing device lengths is shown.
