The function library is still somewhat limited. Implementation of the models in SUPREM will need a significant expansion in this area.
In the future, functions will be added which add and multiply fields and functions. This is a first step providing support for a quasi-fermi net carrier concentration and diffusion enhancements due to interstitial/vacancy supersaturation. It is not clear how to provide for SUPREM models for clustering or other high concentration effects. Suggestions for these are welcome.
