A Variational Formulation for Modeling a Phosphorus Doped Silicon Semiconductor Through a Multi‐Well Approach

Advanced Theory and Simulations, EarlyView.
This article develops a variational formulation for modeling a silicon semiconductor through a multiwell approach utilizing phosphorus atoms as a dopant substance. The variational formulation here developed may be used to find an optimal phosphorus density distribution concerning an originally silicon density, in order to maximize the electrical ...
