Maksymov ABSTRACT The method of finite differences for calculation of avalanche p−n junctions in self-excited oscillation mode is proposed. It is demonstrated that the solution for nonlinear equations set of drift-diffusion model of p−n junctions found with the help of this method is satisfying the boundary conditions at mobile boundaries of the depletion region and the continuity conditions at the boundary of separation of p− and n− regions. The results of calculation of density of charges, electrical field and electrical potential of GaAs avalanche p−n junctions are given.
