Title: Hot Brownian carriers in the Langevin picture: application to a simple model for the Gunn effect in GaAs
Author: Bauke, F. C.
Lagos, R. E.
Abstract: We consider a charged Brownian gas under the influence of external, static and uniform electric and magnetic fields, immersed in a uniform bath temperature. We obtain the solution for the associated Langevin equation, and thereafter the evolution of the nonequilibrium temperature towards a nonequilibrium (hot) steady state. We apply our results to a simple yet relevant Brownian model for carrier transport in GaAs. We obtain a negative differential conductivity regime (Gunn effect) and discuss and compare our results with the experimental results. © 2013 Elsevier B.V. All rights reserved.
