Interband Quantum Cascade Infrared Photodetectors: Current Status and Future Trends
Piotr Martyniuk, Antoni Rogalski, Sanjay Krishna
Abstract
The authors review the past, present, and possible future of interband quantum cascade photodetectors (IB QCPs) based on type-II superlattices of $I\phantom{\rule{0}{0ex}}I\phantom{\rule{0}{0ex}}I\ensuremath{-}V$ semiconductors, in the context of high-operating-temperature (HOT) conditions for infrared technologies. Emerging trends related to IB-QCP detectivity and response time are discussed in terms of commonly used benchmarks, to promote the development of IR HOT optoelectronics.
