A multi-purpose Schrödinger-Poisson solver for TCAD

VSP (Vienna Schrödinger Poisson solver) is a software tool for investigations of novel gate stacks with emphasis on reliability. Numerous technological innovations, including material and process changes such as high-k gate dielectrics and metal gate electrodes, can be analyzed to meet the upcoming scaling requirements while keeping the gate leakage current within tolerable limits.


  • VSP is written in C++ using state-of-the-art software design techniques. Critical numerical calculations are performed with the table and powerful numerical libraries Blas, Lapack, and Arpack.
  • VSP has an open software application interface (API) for the integration within third party simulation environments.
  • Tasks like parameter identification and model calibration, e.g for CV curves and gate stack optimization, can be performed.
