技術摘要 / Our Technology:
A quantum dot infrared photodetector (QDIP) that can enhance the photocurrent to a greater level than the dark current and/or can be operated at high temperatures is disclosed. The quantum dot infrared photodetector comprises at least one quantum well stack and a plurality of quantum dot layers. The quantum well stack is disposed between the pluralities of quantum dot layers. The quantum well stack comprises two spacer layers and a carrier supplying layer. The carrier supplying layer is disposed between the spacer layers. When the quantum dot infrared photodetector is applied with two bias voltages respectively, the carrier supplying layer supplies carriers to the to quantum dot layers.
