Abstract

T2SL (Type II Super Lattice) has become one of the most important material for infrared detector. It has now widely used for HOT MWIR detector and large format LWIR detector. The HOT detector is especially important for satellite application because HOT detector occupies small volume and requires small power. In this work, the radiation test results of MWIR T2SL nbn detector will be presented. The developed hybrid chip has the format of 2048 x 2048 pixels with 10 μm pitch. It was fabricated with Ga-free InAs/InAsSb absorber layer and GaAsSb barrier layer. The quantum efficiency of the developed hybrid chip is larger than 50% and the dark current is below 2 x 10^-8 A/cm². To be used in the space environment condition, the TID (Total Ionizing Dose) effects and DD (Displace Damage) effects were tested and test results are presented.
