Abstract
We propose to develop low cost LWIR FPAs using colloidal quantum dots (CQDs) of II-VI semi-metallic compounds. Brimrose has experience in the area of II-VI semiconductor QD synthesis and LWIR detector fabrication using narrow band gap semiconductor materials. Research Triangle Institute (RTI) in NC has experience in building FPAs using CQDs, and to the best of our knowledge is the only institute that has done this. HgTe QDs are currently limited to detection up to mid-IR wavelengths, while detection in the LWIR 8 to 12 mm range is desired for standoff chemical detection. Growth and characterization of HgTe CQDs under various conditions (temperature, concentrations, ligands, precursors, and procedures) will be done to determine the optimal parameters. We will develop reliable fabrication techniques for the production of HgTe CQDs, and methods to extend the capabilities into the LWIR range will be examined. Also, the design and road map to fabricate an LWIR FPA based on CQDs will be developed. In addition, we will explore the HgSeTe alloy system, as we feel that CDQs of this material have potential as a good LWIR detector material.
