Abstract:
With the rise of cryogenic technologies such as quantum computing [1] and cryogenic power electronics [9], there is a need for better understanding of semiconductor devices at these extreme temperatures. In this thesis, a semiconductor device known as a “Single Quantum Well Light Emitting Diode” is analyzed throughout a wide range of temperatures through IV analysis, and designed for extreme low temperatures through the semiconductor band-engineering technique called “Composition Grading.” The results of this analysis are compared with COMSOL Multiphysics simulations and are found to match well.
