Abstract
Photocapacitive detectors with varying bandgap Hg1-x Cdx Te (604) for two color detection and one color detection with increased potential well capacity. Preferred embodiments include a transparent insulated gate (608) on a top layer (632) of Hg0.8 Cd0.2 Te over a lower layer (634) of Hg0.83 Cd0.27 Te for detection of two infrared colors by varying gate potential to either confine the potential well to the top layer or to extend the potential well to both layers. Also, methods of compositionally grading the Hg1-x Cdx Te by fluid transport plus diffusion.
