Multidimensional modeling of nanotransistors

In this paper, we review our recent work using the nonequilibrium Green's function method to model nanotransistors. After presenting a motivation for the need of quantum mechanical modeling, an account of the equations and implementation is given for both 1-D and 2-D modeling. Examples are given to highlight the use of the developed models. Finally, possible future directions in quantum mechanical modeling of transport in nanotransistors are highlighted along with computational challenges.
