Abstract

We examine transport through several quantum electron waveguide geometries. Reflection and mode-mixing in transmission through bends in quantum waveguides are calculated and the impact on interconnections between devices discussed. We calculate the current-voltage relationship for a constriction in a quantum waveguide for applied voltages beyond linear-response regime. Strong resonance effects in waveguide cavities are found to persist even when cavity geometry is non-abrupt. We demonstrate the existence of current vortices in resonant cavities.
