Abstract
The numerical approach to quantum transport in nanowires and nanotubes in the ballistic regime requires an accurate numerical solution of the coupled Schrödinger and Poisson equations. Here the feasibility of a 5th-order method is proved for the longitudinal part of the wave equation. The effectiveness of the method is demonstrated on a ballistic device.
