Software for Design of Semiconductor Multilayer Structures
Abstract:Three computer programs for calculation of optical and electrical properties of semiconductor multilayer structures are presented. The first program calculates the reflectivity and transmissivity of multilayer structures made of AlAs and GaAs alloys. The second program calculates the energy levels and wave functions in arbitrary one-dimensional potential profiles that can represent either the conduction or valence band of a semiconductor multilayer structure. The third program solves self consistently the Schrodinger and Poisson equations in one dimension for a semiconductor multilayer structure with a given density of electron-hole pairs. This program also calculates the quasi-Fermi levels and the degree of overlap of electron and hole wave functions. The programs are written in C++ language.
