Abstract

The anisotropy of moisture erosion was observed in CH₃NH₃PbI₃ single crystals. When exposed to moisture, the (001) facet exhibited greater sensitivity to water molecules and showed a faster erosion rate compared to the (100) facet and (112) facet. Structural and chemical origins responsible for anisotropic moisture erosion were elucidated.
