Adroit Materials STTR Phase II Award, February 2020

The objective of this project is to develop a compact and efficient avalanche photodiode (APD), operating between 210-260 nm, for implementation in the next generation bio-chem-detectors. The proposed detectors will be based on the AlGaN materials system and will be solar blind, highly sensitive, smaller, less expensive, and more robust than current UV detectors. Development of such APDs will enable enhanced detection and discrimination of biological and chemical compounds (e.g., nerve agents, explosives, or bacteria) using Raman spectroscopy. Results from this project will complement previous achievements from DARPA in the field of UV light sources (LUSTER) and find immediate application in the military and commercial sector.
