ABSTRACTThis project will use the Surface Forces Apparatus (SFA) and various electro-optical and x-ray characterization techniques to develop a novel processing method for producing ultra-thin single-crystal films of conducting/semi-conducting organic compounds and nanoparticle films. The new method is based on preliminary results in which applying pressure, rolling and shear to confined organic-liquid films and nanoparticles dispersed in various organic solvents resulted in highly uniform well-ordered nano-thin layers over large areas. Various parameters will be investigated during this new type of mechanical processing in comparison to conventional wet (self-assembly) methods. The SFA allows one to perform simultaneous mechanical and opto-electronic characterization of thin films in situ. The aim will be to adapt this new processing method for efficient large-scale production of high area displays, organic thin film transistors (OTFT), and high area pressure-sensitive QD displays such as touch panels and new light emitting applications. This proposal is being funded by the Chemical and Transport Systems DivisionParticulate and Multiphase Processes and Interfacial, Transport and Thermodynamics Programs

摘要本计画将利用表面力装置（SFA）及各种光电与x光表征技术，发展一种新颖的制程方法，以制造导电/半导体有机化合物的超薄单晶薄膜与奈米粒子薄膜。新方法是基于初步结果，其中施加压力，滚动和剪切限制有机液体膜和纳米粒子分散在各种有机溶剂中，导致在大面积高度均匀有序的纳米薄层。各种参数将在这种新型的机械加工相比，传统的湿（自组装）的方法进行了研究。该SFA允许一个同时进行机械和光电表征的薄膜原位。其目的是使这种新的处理方法适用于大面积显示器、有机薄膜晶体管（OTFT）和大面积压敏QD显示器（如触摸面板和新的发光应用）的高效大规模生产。该提案由化学和运输系统部颗粒和多相过程以及界面、运输和热力学计划资助
