Charon is an open-source semiconductor device modeling code, widely referred to as a TCAD (technology computer-aided design) code, developed at Sandia National Laboratories. It is written in C++ and relies on another Sandia open-source project, Trilinos, for supporting code, such as nonlinear and linear solvers, finite-element and finite-volume libraries, I/O, etc. In addition to running on most Linux-based computers Charon also supports simulation of extremely large problems on massively parallel computing systems that support the MPI standard.
