| Abstract: | The CdZnTe detectors have the advantages of good intrinsic energy resolution, high detection efficiency and room temperature operation, therefore have attracted much interest in the field of radiation detection. This article introduces the properties of CdZnTe crystal materials and the working principle of the detectors, reviews the application and development of single polarity charge sensing technique in the CdZnTe detectors.Based on the Shockley-Ramo theorem, the principle of single polarity charge sensing technique is explained. The typical unipolar electrode structures in the CdZnTe detectors are introducedandthe latest progress and performance of each electrode structures are summarized. |
