英文摘要	Radiation detectors with different thickness are needed to detect gamma rays with various energies. In this paper, a post-growth annealing method was used to improve the properties of CdMnTe: In (CMT: In) crystals with different thickness for gamma-ray detectors. The results indicated that Te inclusions in CMT: In crystals with different thickness were reduced remarkably after annealing. Both the resistivity and IR transmittance of annealed CMT: In crystals with different thickness increased obviously, which suggested that the crystal quality was improved. For the detectors fabricated by annealed CMT: In slices with 1 mm, 2 mm and 5 mm thickness, the energy resolutions were enhanced about 252%, 193% and 141%, respectively. And (mu tau)(e) values were enhanced about 80%, 80% and 76%, respectively. The performance of the detectors was greatly improved after annealing. (C) 2017 Elsevier B.V. All rights reserved.
