摘要：

We demonstrate a long wavelength (lambda(c) = 20 mum) quantum well infrared photodetector using nonlattice matched InxGa1-xAs/GaAs materials system. High optical gains (low capture probabilities) were achieved by using GaAs as a barrier material in this system. A detectivity of D* = 9.7 X 10(10) cm square-root Hz/W at T = 10 K has been achieved.
