Abstract

CdTe has a wide range of applications in nuclear radiation detectors. However, it will be seriously damaged by irradiation in space and easily lead to device failure. This article primarily focuses on using two software packages in SRIM (Stopping and Range of Ions in Matter) to simulate and study the irradiation damage of CdTe materials. The penetration abilities of irradiated H ions, He ions, and Ar ions inside CdTe crystals were studied firstly. And H ions were selected because of its irradiation damage was distributed wholely inside CdTe crystals. Then, the ion irradiation depth, ion distribution position, and vacancy generation under various energy and dose of H ions were studied. And ²⁴¹Am energy spectrum responses and charge induction efficiency (CIE) of CdTe detectors influenced by H ion irradiation were investigated. The research results are contributive to improve the application of CdTe detectors in the filed of nuclear radiation detection.

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
