Wide Band-gap Radiation Detectors
All dates for this event occur in the past.
Raymond Cao, Ph.D., Professor and Nuclear Engineering Program Director, The Ohio State University
ABSTRACT: Wide band-gap (WBG) semiconductors offer stability, endurability, and room temperature operation than those narrow band-gap semiconductors such as Si and Ge detectors. One example of most developed WBG is the well-known CZT detector. One emerging WBG is lead halide perovskites that show a great potential in X- and gamma-rays detection with a desirable high attenuation coefficient, a wide band gap energy, and a large mobility-lifetime (mt) product. The all-inorganic CsPbBr3 perovskite has its own advantages due to the structural stability over the organic-inorganic perovskites. Other thin-film WBG such as SiC offers the rad-hardness and high temperature resistance that are suitable for nuclear fuel cycle applications. This talk will be focused on the development of WBG detectors and their applications in nuclear fuel cycle such as pyro-processing.
