Abstract

This thesis aims to develop a suite of computational tools for design, analysis, and simulation of semiconductor multiple quantum well structures with a user-friendly GUI. The research project focuses on the electrical and optical aspects of user defined quantum well structures, and allows the user to vary design parameters to optimize the structure for different device applications and functionality. Specifically the thesis delves into the design and analysis of different quantum well structures as they relate to band gap engineering. Key features of this computational suite include relationship to electrical field, doping profiles and optical transitions. The quantum well structures presented are single, double, stepped, and chirped quantum wells, with uniform, modulated, or planar doping. The computational suite can be applied to the calculation of energy levels and band bending in intraband and interband optical transitions in quantum well infrared photodetectors (QWIPs) and quantum well electroabsorption and electroreflection modulators.
