Abstract

CdZnTe (CZT) is a new type of compound semiconductor that has emerged in recent years. Compared to other semiconductor materials, it possesses an ideal bandgap, high density, and high electron mobility, rendering it an excellent room-temperature composite semiconductor material for X-ray and γ-ray detectors. Due to the exceptional performance of CZT material, detectors manufactured using it exhibit high energy resolution, spatial resolution, and detection efficiency. They also have the advantage of operating at room temperature. CZT array detectors, furthermore, demonstrate outstanding spatial detection and three-dimensional imaging capabilities. Researchers worldwide have conducted extensive studies on this subject. This paper, building upon this foundation, provides a comprehensive analysis of CZT crystals and CZT array detectors and summarizes existing research to offer valuable insights for envisioning new detector methodologies.

摘要

碲锌镉（CZT）是近年来出现的一种新型化合物半导体。与其他半导体材料相比，它具有理想的带隙、高密度和高电子迁移率，使其成为用于X射线和γ射线探测器的优秀室温复合半导体材料。由于CZT材料的卓越性能，使用它制造的探测器具有高能量分辨率、空间分辨率和探测效率。它们还具有在室温下工作的优势。此外，CZT阵列探测器具有出色的空间探测和三维成像能力。世界各地的研究人员都对这一课题进行了广泛的研究。本文在此基础上，对CZT晶体和CZT阵列探测器进行了全面分析，并总结了现有研究，为设想新的探测器方法提供有价值的见解。
