摘要：

We have measured the optical and transport properties of In0.2Ga0.8As/GaAs quantum well infrared photodetectors based on bound-to-bound, bound-to-quasibound, and bound-to-continuum intersubband transitions. Excellent hot electron transport and high detectivity D*=1.8X10(10) cm square-root Hz/W (at lambda(p)=16.7 mum) were achieved at temperature T=40 K.
