Abstract

Metal halide perovskite semiconductors are promising materials for direct-conversion radiation detection. However, their development faces challenges in growing sufficiently large crystals and rapidly characterizing detector arrays. Prior approaches to growth of large crystals have focused on chemical methods of controlling growth rates and nucleation, and most readout methods employ expensive integrated circuits with limited flexibility. A computer vision system was developed to track the growth of single crystals, providing insights into methods of growing large crystals and eliminating nucleation. Further, a readout system based on a precision switching topology was developed to allow for low cost, flexible evaluation of detectors. These two systems address key problems impeding the research of perovskite radiation detectors in the intermediate stage, allowing for improved growth processes and rapid evaluation of integrated detectors.
