The software project kdotpy aims at simulations of electronic band structures of semiconductor devices with k·p theory. The application implements the widely used Kane model, capable of reliable predictions of transport and optical properties for a large variety of topological and non-topological materials with a zincblende crystal structure.
In this presentation, I present the core functionality and features of kdotpy. I will explain how we have implemented principles of modern software engineering and good scientific practice in this project.
