Electron-number statistics and shot-noise suppression by Coulomb correlation in nondegenerate ballistic transport Bulashenko, Oleg Mateos López, Javier Pardo, D. González, T. Reggiani, L. (Lino), 1941- Rubí Capaceti, José Miguel Transport d'electrons Soroll electrònic Física estadística Electron transport Electronic noise Statistical physics Within a Monte Carlo simulation, we investigate the statistical properties of an electron flow injected with a Poissonian distribution and transmitted under ballistic regime in the presence of long-range Coulomb interaction. Electrons are shown to exhibit a motional squeezing which tends to space them more regularly rather than strictly at random, and to evidence a sub-Poissonian statistics with a substantially reduced Fano factor Fn!1. The temporal ~anti!correlation among carriers is demonstrated to be a collective effect which persists over the transit of several successive electrons, and results in a considerable ~more than one order of magnitude! shot-noise suppression. 2009-12-29T11:33:25Z 2009-12-29T11:33:25Z 1998 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0163-1829 https://hdl.handle.net/2445/10663 143460 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevB.57.1366 Physical Review B, 1998, vol. 57, num. 3, p. 1366-1369 http://doi.org/10.1103/PhysRevB.57.1366 (c) The American Physical Society, 1998 info:eu-repo/semantics/openAccess 4 p. application/pdf application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
