Methods and structures of barrier detectors are described. The structure may include an absorber that is at least partially reticulated. The at least partially reticulated absorber may also include an integrated electricity conductivity structure. The structure may include at least two contact regions isolated from one another. The structure may further include a barrier layer disposed between the absorber and at least two contact regions.

Low cross-talk for small pixel barrier detectors

An infrared radiation ('IR') focal plane array ('FPA') imager includes a detector array chip containing pixels having substantially one-hundred percent operability. Each of the pixels contains a plurality of interdigitated sub-detectors, where the sub-detectors are selectively operable to provide for collection of photogenerated minority charges representative of all or substantially all of the IR radiation absorbed by the detector array chip of the FPA imager.

Electromagnetic energy is detected with high efficiency in the spectral range having wavelengths of about 1&#x2013;2 microns by coupling an absorber layer having high quantum efficiency in the spectral range having wavelengths of about 1&#x2013;2 microns to an intrinsic semiconducting blocking region of an impurity band semiconducting device included in a solid state photon detector.
