  "abstract": "Metal halide perovskite single crystals stand out for their exceptional optoelectronic properties, and targeted facet regulation is a key pathway to further elevate their device performance by leveraging the anisotropic characteristics of different crystallographic planes. However, existing protocols for preferentially growing (110)-faceted MAPbBr3 single crystals require precise stoichiometric control, complex temperature programming, or time-consuming processes, hindering their reproducible and scalable fabrication. In this work, we develop a facile seed-assisted isothermal solvent evaporation strategy to prepare MAPbBr3 single crystals with preferential (110) facet exposure, using isopropyl alcohol (IPA) as a multifunctional growth additive at a fixed temperature of 47 °C. Experiments and theoretical calculations reveal that the three synergistic roles of IPA—surface coordination to stabilize growth kinetics, solubility-induced reduction in the effective MABr/PbBr2 ratio, and facet-selective adsorption to modulate relative growth rates—collectively enable the controlled growth of MAPbBr3 SCs with large-area (110) facet exposure. The as-prepared (110)-faceted crystals exhibit lower defect density and longer carrier lifetimes than their conventional (100)-faceted counterparts. When assembled into X-ray detectors, the (110)-based devices deliver a sensitivity of 10,532.9 μC Gyair−1 cm−2 and a limit of detection of 0.18 μGyair s−1, corresponding to a ~3.7-fold sensitivity improvement and a 45-fold detection limit reduction relative to (100)-based devices. This work provides a reliable and facile approach for perovskite single-crystal facet engineering and advances the development of low-dose, high-sensitivity X-ray detection technology.",
