Sub-Poissonian shot noise in non-degenerate diffusive conductors
arXiv:cond-mat/9810117 · doi:10.1103/PhysRevLett.82.2761
Abstract
A theory is presented for the universal reduction of shot noise by Coulomb repulsion, which was observed in computer simulations of a disordered non-degenerate electron gas by Gonzalez et al. (cond-mat/9803372). The universality of the reduction below the uncorrelated value is explained as a feature of the high-voltage regime of space-charge limited conduction. The reduction factor depends on the dimensionality d of the density of states, being close but not quite equal to 1/d in two and three dimensions.
