Inkjet-printed short-channel polymer transistors exhibit a high performance (μavg = 1.20 cm(2) V(-1) s(-1) ). With a 50 μm orifice nozzle, polymer transistors with a sub-micrometer (700 nm) channel length are mass-fabricated with good uniformity and reproducibility. In addition, owing to the device geometry, an ultrahigh photoresponsivity up to 10(6) A W(-1) is achieved, which realizes economical, lithography-free photodetectors.
喷墨打印短沟道聚合物晶体管表现出优异的性能（μavg = 1.20 cm(2) V(-1) s(-1)）。采用 50 μm 喷孔喷嘴，可大规模制备具有亚微米（700nm）沟道长度的聚合物晶体管，且具有良好的均匀性和可重复性。此外，由于器件的几何形状，实现了超高的光响应率，高达 10(6) A W(-1)，从而实现了经济、无需光刻的光电探测器。
