A Low-Cost, High-Performance Colloidal Quantum Dot long wave infrared focal plane array for Hyperspectral Imaging
University of Chicago, IL, United States
Infrared imaging devices with higher operating temperatures and lower cost are sought. Researchers have developed HgTe quantum dot photodetectors with a room-temperature photoresponse beyond 5 Âµm, the longest interband absorption wavelength reported for colloidal materials Operation covering the important atmospheric mid-wavelength infrared window between 3 and 5 Âµm is demonstrated.
Primary Application Area: Electronics, Sensors & Communications
Technology Development Status: Prototype
Technology Readiness Level: TRL 3
FIGURES OF MERIT
Value Proposition: The materials currently used in mid-wavelength infrared (MWIR) detectors provide good quantum efficiencies, but remain expensive and require cooling. HgTe colloidal quantum dots (CQDs) offer significant advantages over epitaxial dots due to the much higher achievable packing density and greater ease of processing.
