Suppressing Ion Migration in Heterostructure Single Crystals for Highly Sensitive Ultra-Stable X-Ray Detection.

ABSTRACT: Heterostructure single crystals have emerged as a significant functional material system due to their unique properties and potential for novel optoelectronic device applications. Particularly, their distinctive structural characteristics offer promising prospects for suppressing ion migration, which is highly advantageous for X-ray detection. Herein, by gradually modifying the cyclohexylmethylamine cation into the 4-aminomethyltetrahydropyran cation, a layered heterostructure single crystal (PbCl₂)₂(4-Aminomethyltetrahydropyran)₂PbCl₄ is successfully obtained. It comprises two distinct inorganic frameworks, namely a perovskite layer built from PbCl₆ octahedra and an intergrowth layer consisting of PbCl₂ units, wherein the organic components are
