Abstract :
Recent experimental results and simulations of planar CZT detectors with capacitive Frisch grids are presented. A computer program which incorporates material properties, device design, and operating conditions was developed to simulate device performance. Simulated spectra were compared with measured spectra. Energy resolution of 1.7% at 662 keV was obtained at room temperature for a device with dimensions of 5 mmtimes5 mmtimes10 mm. Spectra also were compared with spectra from a scintillator/photodetector
