May 4th, 2022: ViennaSHE 1.3.0 released! (Changelog)
ViennaSHE is a free, multi-dimensional semiconductor device simulator using Spherical Harmonics Expansions for deterministic numerical solution of the Boltzmann Transport Equation. The method provides much shorter execution times than Monte Carlo methods at comparable accuracy, thus making it an ideal candidate for next-generation TCAD. In addition to traditional macroscopic models such as drift-diffusion, which can also be solved using ViennaSHE, the full carrier distribution functions are computed. This provides full information about the carrier energy distribution, which is for example of utmost importance for the study of hot carrier degradation.
ViennaSHE is developed in joint research projects at the TU Wien by the groups of
