Abstract
We consider transport in a quantum-coherent system containing a ballistic region and disordered reservoirs connected to it. The ballistic region works as a filter: It suppresses conductance fluctuations that are due to disorder and recovers conductance quantization. However, the suppression is much weaker than that predicted by Ohm’s law for classical resistors in series.This publication has 38 references indexed in Scilit:
