Abstract
Barrier infrared detectors having structures configured to enhance the quantum efficiency, and methods of their manufacture are provided. In particular, device structures for constructing high-performance barrier infrared detectors using novel combinations of p-type and n-type absorber regions and contact regions are provided. The infrared detectors generally incorporate a 'pBpnn' structure. The detectors generally comprise, in sequence, a highly p-doped contact layer 'p', an electron unipolar barrier “B”, a p-type absorber section “p”, and n-type absorber section “n”, and a highly n-doped contact layer “n”.
