Abstract
We report a longwave infrared quantum dot infrared photodetector working at room temperature (RT) (298K). A high photoresponsivity and photodetectivity of 0.02A/W and 9.0x106 cmHz1/2/W were achieved at 298K with a low bias voltage of -0.1V. The RT QDIP avoids bulk and heavy cryogenic cooling systems and thus enables the development of ultra-compact IR sensing and imaging systems.
