摘要：
A fully quantum-mechanical model for electron transport in quantum-well infrared photodetectors (QWIPs) is presented, based on a self-consistent solution of the coupled rate equations. The important macroscopic parameters like current density, responsivity, and capture probability can be estimated directly from this first-principles calculation. The applicability of the model was tested by comparison with experimental measurements from a GaAs/AlGaAs device, and good agreement was found. The model is general and can be applied to any other material system or QWIP design. (C) 2004 American Institute of Physics.
