Influence of the minimization of self-scattering events on the Monte Carlosimulation of carrier transport in III-V semiconductors

This paper presents a procedure to improve the algorithm of Sangiorgi, Ricc o and Venturi for the calculation of the time of flight in Monte Carlo simu lations. The method is used to efficiently optimize the step function in wh ich the total scattering probability is discretized. The optimization crite rion suggested in this work can reduce the self-scattering events to less t han 30% in a fairly wide range of temperatures, applied fields and doping l evels. Different examples are presented to illustrate the advantages of the method.
