Key Points

Investigate how crystal orientation affects the degradation of MAPbBr2.5Cl0.5 single crystals when exposed to X-ray irradiation.
Analyzed lead halide perovskite single crystals under controlled X-ray irradiation conditions.
Measured charge carrier generation and degradation patterns across different crystal orientations.
Utilized imaging techniques to assess crystal integrity post-irradiation.
Significant variations in degradation rates were observed depending on the crystal orientation.
Optimal orientations demonstrated better stability and higher charge carrier retention under X-ray exposure.

Implication

This analysis shows how crystal orientation influences degradation under X-ray radiation, highlighting potential enhancements in detector materials.

Abstract

Lead halide perovskite single crystals have demonstrated significant potential for X-ray and gamma-ray detection. While these high-energy photons generate charge carriers within the crystal, they also induce irradiation damage, a...
