Multi-color double-barrier superlattice infrared photodetector combined with quantum well infrared photodetector for operation at high temperature and low bias

摘要

This work presented multi-color infrared photodetector for operation at high temperature and low bias. The BLIP temperature is about 100K and the photoresponse is 12mA/Wat 110K under 0.3V. This device is the promising candidate of a pixel in the focal plane array.
