Quantum Dot Interdiffusion For Two Colour Quantum Dot Infrared Photodetectors

Kuffner, Peter


An investigation into the effects of thermal interdiffusion on the characteristics of quantum dot infrared photodetectors (QDIPs) yields results useful for the creation of a two-colour QDIP. For high temperature rapid thermal annealing, quantum dot interdiffusion is induced, resulting in a large wavelength redshift in the photodetector spectral response, at the cost of a small degradation in device performance. The evaluation of a two-colour QDIP fabricated using selective suppression of...[Show more]
