Abstract :
A phase-space-step trajectory calculation within the scheme of self-scattering is presented. In addition, impurity scattering is approximated by the inverse microscopic relaxation time of the Ridley model. The resulting Monte Carlo algorithm is faster by a factor in the order of 15 than one, which integrates the equations of motion via a second-order Runge-Kutta technique and treats impurity scattering rigorously
