Investigation of polymer controlled solution grown single crystal organic-inorganic hybrid perovskites for gamma detection applications

Recently, halide perovskite semiconductors have received due attention as promising materials for radiation detectors. The state-of-the-art room temperature radiation detectors based on CdZnTe are costly; moreover, further improvements in the size and quality of CdZnTe single crystals are restricted due to the appearance of a secondary phase during the crystal growth. Excellent optoelectronic properties of organic-inorganic halide perovskites qualify them to be low-cost and efficient alternative materials for detection of ionizing radiation. The relative ease of growing halide perovskite single crystals using a solution technique makes them attractive for future applications. We report a high-quality single crystal organic-inorganic hybrid perovskites (ScOIHP) grown through a polymer-controlled solution method. The process of detector fabrication using single crystals of CH₃NH₃PbBr₃ (MAPbBr₃) and CH(NH₂)₂PbBr₃ (FAPbBr₃) will be presented. The detector testing using photon sources will be discussed. Finally, the readiness of the as-grown crystals for industrial applications and potential ways for further improvement of ScOIHP synthesis will be discussed.
