Wigner Ensemble Monte Carlo: Challenges of 2D Nano-Device Simulation

We announce a two dimensional WIgner ENSemble (WIENS) approach for simulation of carrier transport in nanometer semiconductor devices. The approach is based on a stochastic model, where the quantum character of the carrier transport is taken into account by generation and recombination of positive and negative particles. The first applications of the approach are discussed with an emphasis on the variety of raised computational challenges. The latter are large scale problems, introduced by the temporal and momentum variables involved in the task.
