Abstract
The range of mid-infrared barrier photodetectors has been extended to cover the whole 3-5 μm atmospheric transmission window by researchers at Jet Propulsion Laboratory (JPL) at California Institute of Technology in the US. By incorporating self-assembled quantum dots into the absorber of the photodetector, they increased the cutoff wavelength from 4.2 to 6 μm and demonstrated an infrared response at temperatures up to 225 K.
