Advancing Infrared Detection for the Air Force
Team promises sophisticated apparatus for the Air Force and space exploration.

Dr. Eui-Hyeok Yang is collaborating with Dr. Stefan Strauf to research the potential of graphene-based sensor materials for improving IR detection. The team led by Dr. Yang has won a grant from the Air Force Office of Scientific Research (AFOSR) to make IR detection technology more versatile with bilayer graphene micro-ribbons (BGMRs) that can be tuned to respond to different wavelengths of infrared radiation.

Harnessing Graphene's Potential
NSF grant supports graphene nanoelectronics research.

Stevens researchers investigate the properties of actively controlled graphene nanoribbon arrays that researchers can "tune" for use in IR detectors covering an ultra-wide spectral range. In their awarded research, they investigate nanoelectromechanical devices employing graphene nanoribbons to significantly improve IR detection schemes. Current IR detectors experience both limitations in their spectral range, for those that rely on the fixed IR absorption properties of detector materials, or their general sensitivities, in the case of tunable thermal detectors.
