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

Jolley, G; Fu, Lan; Jagadish, C.; Tan, Hark Hoe


We report on the effects of the quantum well(QW) thickness on the spectral response and other characteristics of In₀.₅Ga₀.₅As/GaAs/Al₀.₂Ga₀.₈Asquantum dots-in-a-well infrared photodetectors grown by low-pressure metal-organic chemical vapor deposition. The main device properties are observed to have a strong dependence on the QW parameters.
