INHIBITION OF ELASTIC AND INELASTIC-SCATTERING BY THE PAULI EXCLUSION-PRINCIPLE - SUPPRESSION MECHANISM FOR MESOSCOPIC PARTITION NOISE

A semiclassical Monte Carlo simulation which implements a dynamic feed back process based on the Pauli exclusion principle is used to study t he suppression of partition noise in a one dimensional mesoscopic cond uctor. The purely distributed elastic scattering case exhibits a one-t hird suppression relative to full shot noise. Increasing inelastic sca ttering can initially increase the noise, but eventually suppresses it . The key mechanism is the redistribution of electrons by random scatt ering subject to a ''Pauli exclusion principle.'' (C) 1997 Published b y Elsevier Science Ltd.
