Publications

Over the years we published many papers on using the Wigner function for quantum transport in electronics -- see below. If you are using our WEMC simulation software, we would appreciate if you could cite (aside from this web page) the following two papers, which discuss the fundamental computational aspects of the simulator in 1D as well as the critical parallelization approach for 2D problems:
