中文摘要： 下一代的电子器件需要能在较大面积及多种基底上无所不在、随时随地进行计算，薄膜晶体管的重要作用会逐渐彰显。有机薄膜晶体管具有柔性好、重量轻、制作工艺简单、批量生产成本低等优点，但同时也具有载流子迁移率低、饱和电流小、易受外界条件影响等缺点。结合一维纳米材料的高迁移率和高分子柔性基底的廉价、轻薄、柔性，制作柔性薄膜晶体管将前景广阔。本项目主要探索一维纳米材料的柔性薄膜晶体管的制作与性能。通过对催化剂及基底等反应条件的设计控制获得高密度的一维纳米材料阵列，结合控制转移技术、化学合成以及纳米加工等手段将高温苛刻环境下制备的一维纳米材料保持原貌地转移到不耐高温的柔性基底上。进而建立在柔性基底上构建大面积、高性能一维纳米材料基柔性薄膜晶体管的有效方法，并探索器件性质与器件结构的关系。该项目的开展将为新一代器件结构构建的研究奠定一定的基础。

英文摘要： The goal for the next generation of electronic devices is to compute in larger, various substrates at everywhere, anytime and anywhere. The role of thin-film transistor will more important than ever. Organic thin-film transistor has lots of merits, such as flexible, light weight, simple production process, low-cost mass production. However,it also has some shortcomings, such as low carrier mobility, small saturation current, vulnerable to external conditions. It would have broad prospects if we combine the high mobility of one-dimensional nano-materials and low-cost, light weight, flexible polymer substrate to fabricate flexible thin-film transistor. The main goal of this project is to explore the fabrication and performance of one-dimensional nano-material flexible thin-film transistor. To synthesize high-density one-dimensional nano-materials array through the design of catalyst, substrate and other reaction conditions. Combined with the transfer control technology, chemical synthesis and nanofabrication methods, the one-dimensional nano-materials synthesized at high temperature can be transferred to thermolabile flexible substrate and maintain the original appearance. And then to develop an effective methods to build large area, flexible, high-performance one-dimensional nano-materials thin film transistor and to explore the relations between performance and structure of the devices. This project will lay the foundation for new generation of nano-materials devices.
