Quantum dot infrared photodetectors (QDIPs) offer normal-incidence sensitivity, low dark current, high-temperature operation, and multi-wavelength detection. In general, the advantages of these intersubband devices are the result of three-dimensional quantum dot (QD) electron confinement. It is found that the use of AlAs/Gaas SL barrier in an InAs QDIP heterostructure has led to significant gains in the control of detector performance, particularly in terms of obtaining high responsivity from these devices.
