Growth and Characterization of CsPbX₃ Perovskite Semiconductor Crystals for Room Temperature Gamma-Ray Detectors

In this paper we will present the latest growth and characterization of CsPbX<inf>3</inf> crystals for room temperature gamma-ray detection and imaging. Material purification, synthesis, crystal growth from $16-\mathrm{mm}$ to $35-\mathrm{mm}$ diameter, sample preparation, and detector characterization will be presented. We have managed to grow single crystals, free of polarized planes, with resistivity $\gt$ $6.0 \times 10^{9} \Omega$-cm and $\mathrm{mt}_{\mathrm{h}}\gt2.0 \times 10^{-4} \mathrm{~cm}^{2} / \mathrm{V}$.
