摘要
We develop a novel numerical method for solving the Wigner equation which does not rely upon evaluation of the Wigner kernel and utilizes quantum trajectories. This method is a generalization of the effective potential approach widely used in semiconductor TCAD tools while also solving the full Wigner equation. The method’s accuracy is demonstrated with several standard examples.
