Abstract
The third generation of infrared detectors has seen a lot of emphasis been placed on Higher Operating Temperature (HOT) devices. In our research group, we are investigating barrier engineering in two promising material systems namely the type II strained layer superlattices and quantum dots in a well (DWELL) heterostructure. In this paper, we will outline some of our recent approaches to use barrier engineering to obtain a lower dark current and higher operating temperature in these devices.
