Abstract
In this paper, a high operating temperature (HOT) broadband InAs/GaAs quantum dot (QD) infrared photodetector (QDIP) is reported. The QDIP covers a wide detection spectrum range from 3 μm to 10 μm. A large photoresponsivity of 12.0 A/W at a low bias voltage of 0.15V and a high peak specific photodetectivity D* of 1.2×108 cmHz1/2/W are obtained at a high operating temperature of 298 K.
