➀ Researchers developed vapor-deposited tin-halide perovskite thin-film transistors (TFTs) using PbCl₂ to enhance performance and stability;
➁ The TFTs achieved high hole mobility (33.8 cm²/V·s) and on/off current ratios (~10⁸), outperforming solution-based methods and commercial IGZO transistors;
➂ This scalable process holds potential for low-cost, large-area electronics and energy-efficient OLED displays, with future focus on materials optimization and 3D integration.
