Compact Capping Layer Halide Perovskite

X-ray sensitivity 22,245

This capping layer is directly grown on MAPbBr₃ single crystals via a gas-phase method with nanoscale precision and larger steric hindrance, significantly suppressing ion migration, reducing trap states, and enhancing stability, leading to X-ray detector performance among the highest reported.
