Abstract

We study theoretically the effect of few elastic scatterers on electron transport in the ballistic regime. In laterally confined structures (quasi 1-d or 2-d), resonant transmission peaks occur when total electron energy equals any miniband energy. Unit transmission probability is approached when the scattering defect is small, and far from other scatterers, even if the scatterer is strong enough to decrease significantly the conductance away from resonance. Both numerical and analytical methods are used. Resonance occur for all shapes of confining potential.
