Graphene based Dynamically Tunable LWIR Detection and Imaging at Room Temperature

The overall objective is to develop a room temperature LWIR detection and imaging platform with dynamic spectral selectivity option. The 2D material Graphene offers unique opportunity to transfer to a ROIC substrate for seamless integration instead of complex, low yield hybridization. The preliminary research of the graphene based room temperature dynamically tunable longwave IR (LWIR) detector development was funded by DARPA under Wafer Scale Infrared Detector (WIRED) program through Phase-I, Phase-II and Phase-III funding which shows the maturity of the technology for direct Phase-II (DP2) funding from the EPIC-LWIR SBIR program for commercial scale prototype development. E-Skin Displays Inc., California possesses ROIC/TFT experience which will play critical role in developing the prototype of the already proven concept in partnership with University of Central Florida (UCF).  The proposed graphene based asymmetric plasmon-induced hot-carrier Seebeck LWIR detector exhibit an outstanding room temperature responsivity of 2900 V/W, detectivity (D*) of 1.1x109 Jones along with a fast response of ~ 100 ns which surpass performance of all present uncooled IR detectors with unmatched dynamically spectral selective attributes. The proposed work has high potential for commercial development for NASA, USAF, Navy, US Army, Lockheed Martin, Northrop Grumman, FLIR and other related agencies/companies to integrate the technology for space, defense and civilian applications.
