Abstract

We investigate current fluctuations in non-degenerate semiconductors, on length scales intermediate between the elastic and inelastic mean free paths. The shot-noise power P is suppressed below the Poisson value PPoisson = 2 (at mean current Ī) by the Coulomb repulsion of the carriers. We consider a power-law dependence of the elastic scattering time τ α εα on kinetic energy ε and present an exact solution of the non-linear kinetic equations in the regime of space-charge limited conduction. The ratio P/PPoisson decreases from 0.38 to 0 in the range \( - \frac{1} {2} < \alpha < 1 \).
