The Department of Defense, specifically the United States Air Force, is seeking proposals for the Small Business Innovation Research (SBIR) topic titled "Hydrogenation for defect passivation in (Si)GeSn alloys." The objective of this opportunity is to evaluate the effectiveness of post-growth hydrogenation in improving the background carrier concentration and minority carrier lifetime of (Si)GeSn semiconductor alloys, which are critical for infrared-sensing applications. This research is significant as it aims to enhance the performance of photodetection materials by addressing defects that limit device efficiency, particularly in materials grown under non-optimal conditions. Interested parties should note that the solicitation is currently closed, with the release date on April 17, 2024, and the application due date set for June 12, 2024. For further details, please visit the official SBIR website at https://www.dodsbirsttr.mil/topics-app/.
