Modeling Carbon Nanotube FET Physics in COMSOL Multiphysics®
Published in 2008
Carbon nanotube FETs are generating much interest in the nanoscale electronics area. Typically subthreshold behavior in these devices has been modeled using the Laplace equation. Above threshold behavior uses self-consistent solutions to the Poisson and continuity equations. Accurate modeling of Carbon nanotube FETs needs to include quantum effects such as tunneling.
Owing to the coupled nature of modeling this device and the varied physics that need to be modeled, COMSOL Multiphysics is a tool that can be effectively used to model this device. In this paper we explore the ways in which we can model Carbon nanotube FET physics using COMSOL Multiphysics.
