Stability of Charge Collection Efficiency in a Novel Graphene-Optimized Silicon Carbide Detector Under 160 keV X-Ray Irradiation
A graphene-optimized 4H-SiC PIN detector retains 90-97% charge collection efficiency for alpha and beta particles after 1 MGy of 160 keV X-ray irradiation, with only small increases in leakage current and signal rise time.
