ViennaSHE is a free open-source implementation of the SHE method for the simulation of semiconductor devices. It can be used either as a standalone simulator, which is controlled by a configuration provided by a XML file, or as a simulator library, which enables the full flexibility with respect to pre- and post-processing. In the current first release, the calculation of the distribution function of electrons in relaxed silicon neglecting the Pauli principle is provided.

• [NEW] Bipolar solution for electrons and holes including traps
• [NEW] Impact ionization scattering, electron-electron-scattering
• [NEW] Fullband dispersion relation (aka. extended Vecchi model)
• Self-consistent deterministic solver for the Boltzmann transport equation
• Acoustic and optical phonon scattering, ionized impurity scattering
• Parabolic and non-parabolic dispersion relations
• Drift-Diffusion solver provides initial guess for self-consistent SHE simulations
• Support for lines, triangular, quadrilateral, tetrahedral and hexahedral meshes via ViennaGrid
• Parallel linear solver (including GPU acceleration) using ViennaCL
• Both standalone executable (XML file controlled) and use as simulator library (header-only)
• Adaptive variable-order expansions
• Mesh import from Netgen and VTK, export to VTK
• Multi-Platform support
• Permissive MIT/X11 license
