CdZnTe（CZT）作为室温辐射探测器在过去的20 - 30年中一直处于不断发展之中。由于其固有的缺陷，如高浓度的亚晶界网络，它一直是非常具有挑战性的一贯生产高品质的CZT探测器与高产量，特别是探测器的体积超过几个立方厘米。在本文中，我们报告了一个相对较大的体积弗里希栅探测器（尺寸：11 × 10.8 × 19.4 mm 3）的新材料Cd0.9Zn0.1Te0.985Se0.015制造的特性。该探测器是由一个2英寸长的晶锭制成的。通过移动加热器方法生长的直径。通过红外透射显微镜评估检测器样品以研究Te夹杂物的存在。使用同步加速器光源的X射线形貌术被部署来测量亚晶界及其网络的存在。探测器性能的测试是针对优化的Frisch栅长进行的，以在室温下提取最佳的能量分辨率。CdZnTe（CZT）作为室温辐射探测器在过去的2- 30年中一直处于不断发展之中。由于其固有的缺陷，如高浓度的亚晶界网络，它一直是非常具有挑战性的一贯生产高品质的CZT探测器与高产量，特别是探测器的体积超过几个立方厘米。在本文中，我们报告了一个相对较大的体积弗里希栅探测器（尺寸：11 × 10.8 × 19.4 mm 3）的新材料Cd0.9Zn0.1Te0.985Se0.015制造的特性。该探测器是由一个2英寸长的晶锭制成的。通过移动加热器方法生长的直径。通过红外透射显微镜评估检测器样品以研究Te夹杂物的存在。使用同步加速器光源的X射线形貌术被部署来测量亚晶界及其网络的存在。检测器性能进行了测量的优化弗里希网格长度，以提取最佳的能量分辨率在…
CdZnTe (CZT) has been under continuous development as a room-temperature radiation detector for the past 2–3 decades. Due to its intrinsic defects, such as a high concentration subgrain boundary network, it has been very challenging to consistently produce high-quality CZT detectors with high yield, particularly for detector volumes exceeding a few cubic centimeters. In this paper, we report characterization of a relatively large-volume Frisch-grid detector (dimensions: 11 × 10.8 × 19.4 mm3) fabricated from a new material Cd0.9Zn0.1Te0.985Se0.015. The detector was fabricated from an as-grown ingot with a 2-in. diameter grown by the Traveling Heater Method. The detector sample was evaluated by infrared transmission microscopy to study the presence of Te inclusions. X-ray topography using a synchrotron light source was deployed to measure the presence of subgrain boundaries and their networks. The detector performance was measured for an optimized Frisch-grid length to extract the best energy resolution at room temperature.CdZnTe (CZT) has been under continuous development as a room-temperature radiation detector for the past 2–3 decades.
