Abstract :
In this paper we present the results of the theoretical study of static and dynamic properties of multiple Quantum Well Infrared Photodetectors (QWIPs). This study is based on the original model of the QWIPs describing the electron injection from the emitter, transport in the QW structure, and capture (emission) in the QWs in a self-consistent manner. Both static and transient characteristics of the QWIPs are dominated by the contact effects associated with the recharging of the QWs under the applied voltage or infrared radiation
