TechConnect Innovation Program

A Low-Cost, High-Performance Colloidal Quantum Dot long wave infrared focal plane array for Hyperspectral Imaging

University of Chicago, IL, United States

TECHNOLOGY SUMMARY

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 µm, the longest interband absorption wavelength reported for colloidal materials Operation covering the important atmospheric mid-wavelength infrared window between 3 and 5 µm 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.
