Our paper “Dark current mechanisms in ultra-thin mid-wave infrared detectors” was published in J. Appl. Phys. today. This work was led by UT Mid-IR Photonics student Yadviga Tischenko, in collaboration with scientists from Sandia National Labs and our collaborators from the Podolskiy group at UMass Lowell. We look at the dark current mechanisms in ultra-thin mid-wave infrared detectors, and build a qualitative model to explain the absorber doping dependent dark currents observed in our devices. This work provides some clues as to how we might be able to achieve even further reduction in MWIR detector dark currents.
