A wide range of applications, including those of medical and military interest, has fueled research in infrared IR photodetectors. Mercury-cadmium-telluride detectors MCTs are the standard to date, but are often prohibitively expensive and operate optimally at lower temperature as compared with quantum dots based detector. Quantum dot-in-a-well DWELL detectors have emerged as potential competitors to MCTs by combining the advantages of quantum dot detector normal-incidence detection, high photoelectric gain, potential for low dark currents, and high-temperature operation, with those of quantum well detector better sensitivity and control over operating wavelength, and are approaching MCTs in terms of responsivity and specific-detectivity although DWELL detectors still exhibit worse performance than MCTs.
