Infrared Sensing Using Mercury Chalcogenide Nanocrystals
Résumé
his chapter focuses on infrared sensing technology based on mercury chalcogenide (NC) nanocrystals. It begins with a discussion of methods to improve NC film conductivity and then describes the structure, operation and performance of photoconductors, phototransistors and photodiodes made with NCs. In each case, we attempt to highlight the current best performing devices. Finally, we address three emerging directions for research: light-matter coupling, focal plane arrays and intraband detectors.
