The Gunn effect in narrow-band conductors
Abstract
An exact theory of the Gunn effect in narrow-band conductors at high temperatures is developed, based on a solution to the Fokker-Planck equation for the kinetics of heavy particles in a strong electric field. Explicit analytical solutions are obtained for the structure of the moving Gunn domains, and the stability of the moving domains was examined. The effect of thermal diffusion on the velocity of the domains was investigated. The feasibility of observing the Gunn effect in experiments with various types of narrow-band conductors is discussed.
