摘要
A lattice-anchoring strategy using low-dimensional perovskite addresses structural instability in α-formamidinium lead iodide (FAPbI 3 ) by matching crystal lattice, mitigating residual stress and tensile strain. Enhanced Pb-I bonding strength and reduced lattice strain improve structural stability and carrier mobility-lifetime product, enabling efficient charge transport. Optimized X-ray detectors achieve high sensitivity (1.83 × 10 5 μC Gy air –1 cm –2 ), low detection limit (27.6 nGy air s –1 ), and stable performance under prolonged irradiation.
