抄録(和) The barrier infrared detector fabricated with InAs/GaSb type-II superlattice emerges as a solution to a significant reduction in dark current compared to conventional p-i-n photodetectors. In this study, the barrier photodetectors composed of a contact layer, a barrier layer, and an active region (n-type) are evaluated by simulating the two different engineered structures, i.e., pBn and nBn. Numerical simulation results suggest that both structures could be used to reduce the dark current and there exists optimum doping density. We discuss the physical mechanisms behind the observed characteristics.
