Abstract: Compound semiconductor radiation sensors have attracted a sustained research interest due to their great potential for room-temperature X-ray and gamma-ray detection. These detectors are able to deliver excellent energy-resolution and high detection-efficiency while operating at room temperature. These advantages create great opportunities to use such detectors in a wide range of applications including nonproliferation inspections, nuclear-medical imaging, industrial process monitoring, astronomical phenomenon observations, environmental safety and remediation, and basic physics investigations. Central to the movement of compound semiconductor nuclear sensor technologies have been the development of sensor materials and advanced sensor designs. In this seminar I will focus on several important factors that substantially affect the performance of compound semiconductor sensors and discuss the corresponding solutions to address these challenges. The test results from a series of characterization experiments will be presented and their correlation with the integrated device performance will be examined.
Bio: Dr. Ge Yang is Assistant Professor and Group leader of the Radiation Detection Materials and Devices Group at the Department of Nuclear Engineering of North Carolina State University (NCSU). Prior to joining the NCSU faculty, he held the position of Staff Scientist at US Department of Energy’s Brookhaven National Laboratory (BNL), working on Radiation Detectors R&D. Dr. Yang’s research has yielded 7 patent disclosures, 151 publications in top-ranked scientific journals and conference proceedings, and numerous invited presentations at various professional conferences. He is a two-time recipient of the prestigious R&D 100 Award, in 2009 and 2014, together with his collaborators for developing various compact sensors to detect and image radiation. He is also the co-Finalist of 2017 R&D 100 Award for developing novel electrode material for radiation detectors. Dr. Yang’s research interests have revolved around the opportunities at the intersection of nuclear engineering, materials science and engineering and electrical engineering.
