We analyze the effect of a random distribution of scatterers, satisfying the conditions for diffusive transport, inside a mesoscopic cavity. We show that in the presence of the scatterers the distribution of the transmission eigenvalues changes from that typical for an empty cavity to that characteristic of diffusive conductors and, consequently, the value of the shot noise suppression factor moves from 1/4 to 1/3.

Abstract
We analyze the effect of a random distribution of scatterers, satisfying the conditions for diffusive transport, inside a mesoscopic cavity. We show that in the presence of the scatterers the distribution of the transmission eigenvalues changes from that typical for an empty cavity to that characteristic of diffusive conductors and, consequently, the value of the shot noise suppression factor moves from 1/4 to 1/3.File in questo prodotto:
