Background limited mid-infrared photodetection with photovoltaic HgTe colloidal quantum dots
- 1. James Franck Institute, 929 E. 57th Street, The University of Chicago, Chicago, Illinois 60637 (United States)
Description
The photovoltaic response of thin films of HgTe colloidal quantum dots in the 3–5 μm range is observed. With no applied bias, internal quantum efficiency exceeding 40%, specific detectivity above 1010 Jones and microseconds response times are obtained at 140 K. The cooled devices detect the ambient thermal radiation. A detector with 5.25 μm cut-off achieves Background Limited Infrared Photodetection at 90 K
