Paper Abstract

Quantum-mechanical model calculations of the conductance G of two parallel ballistic constrictions joining two two-dimensional electron gases show that G is nearly additive. This is due to the continuous distribution of incident modes and the collimation along the constrictions, and is almost independent of the width, length, Fermi energy and detailed shape of the constrictions. Due to coherence effects, the additivity breaks down, but only weakly so, when the constrictions are contiguous and very short and wide.
