摘要：
GaAs/AlGaAs multiple quantum well infrared detectors (QWIPs) are novel detectors based on the optical intersubband transitions between bound-to-bound or bound-to-extended states in conduction band of quantum well structures. They have the advantages of fast response time (on the order of ps), high quantum efficiency, tailorable wavelength and band width, high thermal stability and radiation hardness, which are very useful for fabricating large-area focal plane array (FPA) detectors.
