Resistive Wires Instead of Ideal Leads. Breakdown of the Channel Equipartition Rule

Abstract: A quantum wire with constant cross-section and ideally reflecting lateral boundaries, filled uniformly (on the average) with point-like elastic scatterers in the dilute limit, is considered as an idealized model of a resistive lead. Due to the unavoidable energy and channel dependence of the mean free path, the conducting channels contribute differently to the current which is dominated by the fast channels. This result disagrees with the usual channel equipartition rule for ideal leads fed by reservoirs in st… Show more
