Paper Abstract

In this work, we report on the design, fabrication, and characterization of MWIR unipolar barrier photodetectors based on InAs/GaSb Type-II superlattice. We have designed, fabricated, and characterized band-structure engineered MWIR photodetectors based on the pBiBn architecture. The devices have been characterized using the most relevant radiometric figures of merits. At 200 K, the peak value of detectivity is 1.2 x 1011 Jones at an applied bias voltage of -0.5 V.
