摘要：

The first long wavelength quantum well infrared photodetector based on valence band intersubband absorption holes is demonstrated. A normal incidence quantum efficiency of eta = 28% and detectivity of D-lambda* = 3.1 x 10(10) cm square-root Hz/W at T = 77 K, for a cutoff wavelength lambda-c = 7.9-mu-m, have been achieved.
