We report the low-voltage operation of organic thin-film transistors (OTFTs) based on high-resolution printed source/drain electrodes that are produced by a surface photoreactive nanometal printing (SuPR-NaP) technique. We utilized an ultrathin layer of perfluoropolymer, Cytop, that functions not only as a gate dielectric layer in the OTFTs but also as a base layer for producing a patterned reactive surface for silver nanoparticle chemisorption in the SuPR-NaP technique. We successfully demonstrate 2 V operation with negligible hysteresis in the polycrystalline pentacene OTFT with a gate dielectric thickness of 22 nm, and we achieved current amplification by the printed electrodes modified with pentafluorobenzenethiol. The SuPR-NaP technique enables the production of high-resolution printed silver electrodes required for high-performance OTFTs, which have potential practical electronic device applications.

我们报告了基于高分辨率印刷源/漏电极的有机薄膜晶体管（OTFT）的低压操作，该高分辨率印刷源/漏电极是通过表面光反应性纳米金属印刷（SuPR-NaP）技术生产的。我们利用了全氟聚合物的超薄层Cytop，该层不仅充当OTFT中的栅极介电层，而且还充当基础层，用于在SuPR-NaP技术中产生用于银纳米粒子化学吸附的图案化反应性表面。我们成功地在栅介电层厚度为22 nm的多晶并五苯OTFT中成功地证明了2 V工作时的磁滞可忽略不计，并且通过用五氟苯硫醇修饰的印刷电极实现了电流放大。SuPR-NaP技术可生产高性能OTFT所需的高分辨率印刷银电极，
