Optically transparent and mechanically flexible thin-film transistors have recently attracted attention for next generation transparent display technologies. Driving and switching transistors for transparent displays have challenging requirements such as high optical transparency, large-scale integration, suitable drive current (I(on)) in the microampere range, high on/off current ratio (I(on)/I(off)), high field-effect mobility, and uniform threshold voltage (V(th)). In this study, we demonstrate fully transparent high-performance and high-yield thin-film transistors based on random growth of a single-walled carbon nanotube (SWNT) network that are easy to fabricate. High-performance SWNT-TFTs exhibit optical transmission of 80% in visible wavelength, I(on)/I(off) higher than 10(3), and a high yield with reproducible electrical characteristics.
最近，用于下一代透明显示技术的光学透明和机械灵活的薄膜晶体管引起了人们的关注。透明显示的驱动和开关晶体管具有挑战性的要求，如高光学透明度，大规模集成，适合微安范围内的驱动电流（I（on）），高导通/截止电流比（I（on）/ I（off）），高场效应迁移率和均匀的阈值电压（V（th））。在这项研究中，我们展示了基于单壁碳纳米管（SWNT）网络随机生长的易于制造的全透明高性能和高产率的薄膜晶体管。高性能的 SWNT-TFT 具有 80%的可见光透过率，I（on）/ I（off）高于 10（3），以及具有可重复电特性的高产量。
