Ballistic charge transport in a triple-gate silicon nanowire transistor

Abstract

In this paper we investigate the electrostatics and charge transport in a triplegate Silicon Nanowire transistor. The quantum confinement in the transversal dimension of the wire have been tackled using the Schr¨odinger equation in the Effective Mass Approximation coupled to the Poisson equation. This system have been solved efficiently using a Variational Method. The charge transport along the longitudinal dimension of the wire has been considered using the semiclassical approximation, in the ballistic regime.
