A Pilgrim’s Guide to Semiconductor Energy Bands

The quest to determine the electronic structure of atoms, molecules and condensed matter is as old as quantum mechanics itself. It began as a methodology to understand the properties, both bulk properties, reaction properties and the kinetics of such. Yet, it is often regarded as a difficult, and perhaps esoteric, domain of physics and chemistry. This is problematic as the modern electronic industry has become quite adept at varying material properties through the use of strain, alloying, and heterostructures to improve the operation of the ubiquitous nanocomputer that powers our world. It is instructive to realize that this latter community uses band structure calculations as a guide to continuing the integration described by Moore’s Law. In this talk, I will introduce modern band structure approaches and realms, before concentrating on semiconductor alloys of interest: the alloys AlAsSb and InAlAs.
