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.
