Abstract

This study explores the effects of novel H₂CrO₄-based passivant on Cd_0.95Mn_0.05Te_0.98Se_0.02 (CMTS) detectors. Optimal passivation for 3 min improved spectroscopic performance by addressing surface defects. However, longer passivation led to degradation due to Cr-invasion, as shown by XPS analysis. The use of a virtual Frisch grid further enhanced energy resolution, highlighting the potential of CMTS detectors for high-energy gamma spectroscopy. These findings emphasize the importance of precise passivation control and suggest that improved CMTS fabrication and passivation techniques could advance the development of cost-effective, larger volume CdTe-based detectors for room temperature applications.
