A Backward Monte Carlo Method for Simulationof the Electron Quantum Kinetics in Semiconductors

A quantum‐kinetic equation accounting for the electron‐phonon interaction is solved by a stochastic approach. Analyzed are three analytically equivalent integral formulation of the equation which appear to have different numerical properties. Particularly the path‐integral formulation is found to be advantageous for the numerical treatment. The analysis is supported by the presented simulation results. A variety of physical effects such as collisional broadening and collision retardation introduced by the equation are discussed.
