%X The crystal size and energy resolution of CdZnTe (CZT) detectors are limited by crystal growth technology. In this paper, capacitive Frisch grid detector structure was used to reduce the leakage current and overcome the charge carriers' recombination by the geometric of unipolar charge. The electrode contact of the detector was made of Schottky contact which can further compress the weight of potential and reduce the leakage current noise. A large volume multi-element parallel detector was made by capacitive Frisch grid structure and Schottky contact electrode (In-p/CZT-AuCl3). The energy resolution of multi-element detectors is not limited to the worst energy resolution unit and the detection efficiency is 2.45 ~ 7.31 times more than that of the single unit.
