中文摘要：

由于CdZnTe（CZT）探测器尺寸和能量分辨率受到工艺限制,采用电容性Frisch栅探测器结构,将多个薄的单元探测器并行叠加使其等效为大体积的探测器,用于克服单元小探测器探测效率低的缺点,同时单极电荷的几何结果有效克服了载流子的复合.探测器的电极接触为肖特基接触（In-p/CZT-AuCl3）,进一步压缩了权重势,降低了噪声,降低了漏电流,从而得到大体积多元并行探测器的能量分辨率不受单元能量分辨率最差探测器的限制,并且探测效率为单元探测器的2.45～7.31倍.

英文摘要：

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.
