Presently, inorganic perovskite CsPbBr₃ bulk crystal is considered one of the most promising alternatives to CdZnTe (CZT), the standard room-temperature semiconductor detector (RTSD). This material shows potential not only for use in security and defense, but also in a wide range of industrial, medical imaging, and scientific research applications involving nuclear radiation detection. In this work, we report a room temperature nuclear radiation detector performance far better than CZT in single channel parallel-capacitor-like planar detector form, which is the most realistic form for evaluating the quality of a RTSD material. The material was grown in house at Brimrose Technology Corp by the conventional, cost effective, and scalable Bridgman method. As such, it is a very promising room temperature detector material for next generation defense-related applications, including as backpack detectors for special nuclear material detection, autonomous nuclear detection systems on drones, and other civilian and industrial usages such as scientific research and medical imaging.
