Bandgap Shifting of an Ultra-Thin InGaAs/InP Quantum Well Infrared Photodetector via Rapid Thermal Annealing
We demonstrate that SiO2 cap rapid thermal annealing in ultra-thin p-type InGaAs/InP quantum wells can be used to produce large blue shifts of the band edge. A substantial bandgap blue shift, as much as 292.5 meV...
