Exploring centimeter-sized single crystals of a 2D Dion–Jacobson halide perovskite toward efficient X-ray detection

Abstract

A 2D halide perovskite (1) was syntheized. 1 shows semiconductor properties, such as a high resistivity (6.01 × 1010 Ω cm) and a μτ product (6.21 × 10−4 cm2 V−1), a low LOD of 236 nGyair s−1 and a sensitivity of 270 μC Gyair−1 cm−2 at a 5 V bias.
