T. Gonzalez et al., NOISE SUPPRESSION IN MESOSCOPIC STRUCTURES DUE TO LONG-RANGE COULOMB INTERACTION, Physica status solidi. b, Basic research, 204(1), 1997, pp. 450-452
We present a microscopic analysis of shot-noise suppression due to lon
g-range Coulomb interaction in semiconductor samples operating between
ballistic and diffusive transport regimes. We find that the strong su
ppression observed under the ballistic regime persists under quasi-bal
listic conditions, before being washed out when a complete diffusive r
egime is achieved.
