Quantum well and quantum dot infrared photodetectors: Physics of operation and modeling

摘要

We review recent studies of physical phenomena in quantum well infrared photodetectors (QWIPs), and some other QW and QD infrared devices and discuss their features. We show that the optimization of QWIPs, improvement of QDIPs, and creation of novel QWIP- and QDIP-based devices still requires an in-depth understanding of underlying physical effects.
