Abstract:

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).
