The physical properties of detectors based on intraband optical absorption in quantum dots is described and examined the interest providing a competitive alternative infrared (IR) detector technology. These dot are an extension well photodetectors expected to have large performance advantage. A model developed for fundamental limitations enabling direct comparison between IR materials technologies. made among HgCdTe, well, detectors, where potential outperform wells by several orders magnitude compete with HgCdTe. In this analysis, possess ability achieve highest if arrays high size uniformity optimal bandstructure may be achieved.
