Abstract: We investigated the use of transparent conductive oxide nanoparticles with mercury cadmium telluride photoconductive detectors fabricated by vapor or liquid phase epitaxy. Light concentration is achieved through localized plasmon resonance at the transparent conductive oxide nanoparticles which are deposited to the photodetector surface. In this manner responsivity and specific detectivity are enhanced at infrared wavelengths used for thermal night vision.
