The earlier evaluation, which was based on the predictions of a compact model, is shown to be optimistic because of the model's inadequate treatment of quantum mechanical reflection of thermionically injected carriers. This deficiency of the compact model is remedied, to a large extent, by incorporating a new, short expression for quantum mechanical reflection under phase-incoherent conditions}, keywords = {carbon nanotubes;field effect transistors;nanotechnology;Poisson equation;quantum theory;semiconductor device models;}, URL = {http://dx.doi.org/10.1088/0964-1726/15/1/003}, author = { Castro, L.C. and John, D.L. and Pulfrey, D.L.} }
