Monte Carlo solver

Just wanted to post a quick video of a coupled Monte Carlo transport-Poisson equation solver for a 2D MESFET. The colored background is a heat map of electric field strength, while the white dots represent individual electrons being accelerated and scattered in the device. Sorry for the low quality. YouTube decided that was acceptable, despite having a higher-quality source available. Each frame is 2e-15 seconds, and the total length corresponds to 8e-12 seconds.
