Abstract
With the increasing deployments of smaller instruments for scientific observations from space there is a need for innovative sensors and techniques. These solutions have to be compact, low power, and operate with improved efficiencies. Commercial vendors have been able to produce hyperspectral instruments with various improved capabilities such as incorporating innovative spectrometers, or a single chip with spectral imaging capabilities.

Abstract
Abstract
Using Density Functional Theory (DFT) based simulations we investigate new designs of PbSe-Graphene MWIR detector and their physics. These detectors have three possible distinct modes of operation depending on the interface design, and show promise for scalable, high operating temperature, low noise, CMOS integrable photodetectors.
