Effects of annealing on the properties of In0.5Ga0.5As/GaAs/Al0.2Ga0.8As quantum dots-in-a-well infrared photodetectors

Jolley, Greg; Xiao, B; Fu, Lan; Jagadish, Chennupati; Tan, Hark Hoe


We report on the device parameters of In0.5Ga 0.5As/GaAs/Al0.2Ga0.8As quantum-dots- in-a-well infrared photodetectors annealed at various temperatures from 700 to 850 °C. The temperature dependent dark current-voltage characteristics are found to have a
