Abstract

SCHRED stands for self-consistent solver of the 1D Poisson and 1D effective mass Schrodinger equation as applied to modeling single gate or dual-gate capacitors. The program incorporates many features such as choice of degenerate and non-degenerate statistics for semiclassical charge description, inclusion of the exchange-correlation corrections to the ground-state energy of the system when using quantum model, choice of metal or polysilicon gates, quantization of both electrons and holes, choice of full or partial ionization of the impurity atoms, capacitance calculation, etc. All these features make SCHRED one of the most sophisticated tools for modeling electrostatics in single gate and dual-gate capacitors that are integral part of conventional or dual-gate transistors.
