Simulation of capacitance-voltage characteristics of heterostructures with quantum wells using a self-consistent solution of the Schrodinger and Poisson equations

摘要

Methods are developed for calculating capacitance-voltage characteristics and finding the concentration profile of free charge carriers in semiconductor doped heterostructures containing a quantum well. The capacitance-voltage characteristic of a heterostructure with a quantum well was calculated using a numerical self-consistent solution of the Poisson and Schrodinger equations in the context of a unified quantum-mechanical approach. The suggested method was applied to the simulation and analysis of the experimental capacitance-voltage characteristics of heterostructures with strained InGaAs/GaAs quantum wells.
