摘要
化合物半导体在实验室和光子源光束线应用的 X 射线像素探测器生产中发挥着重要作用。过去几十年来,这些探测器的性能不断提高,但实验仍然受到探测器材料特性的限制,特别是在高通量照明下。包晶晶体的快速发展为新材料用作高效 X 射线像素探测器提供了可能。迄今为止已公布的传输特性数据证明了包晶体半导体的巨大潜力。所达到的数值可与基于碲化镉的探测器相媲美。本文介绍了潜在的光致发光半导体探测器材料,并将其性能与最先进的碲化镉探测器进行了比较。透辉石半导体在生产大面积 X 射线探测器方面前景广阔,但仍存在一些挑战。
Perspective of perovskite-based X-ray hybrid pixel array detectors
Compound semiconductors are playing a major role in the production of X-ray pixel detectors for the application in laboratories and beamlines at photon sources. The performance of these detectors has constantly been improved for the last decades but experiments are still limited by the properties of the detector material, especially under high flux illumination. The fast development of perovskite crystals opens the possibility for new materials to be used as highly efficient X-ray pixel detectors. The published data until now, of the transport properties, demonstrate the large potential of perovskite semiconductors. The achieved values are comparable with the ones of CdTe-based detectors. This paper presents potential perovskite-based detector materials and compares their performance with the state-of-the-art CdTe-based detectors. The perspectives of perovskite semiconductors are promising for the production of large area X-ray detectors but still some challenges remain.
