Abstract :
Crystal quality of radiation detector-grade TlBr material was analyzed by X-ray diffraction and synchrotron X-ray topography methods. The analyzed TlBr crystals were further processed for electrical characterization and current–voltage characteristics were measured at a temperature range of 210–320 K. The crystals studied in this work were grown by the Bridgman–Stockbarger process. X-ray diffraction measurements show the presence of small-angle grain boundaries in the crystals. The crystal with the most pronounced small-angle boundaries showed the lowest resistivity and the poorest spectroscopic characteristics.
