我们报道了一种在室温下形成有机导电复合材料纳米图案化薄膜的技术。这些装置是通过复制一个非光刻生产的模板来形成一个高纵横比的火山状结构。研究了这些结构的场致发射，发现它们提供了约250的场增强。发射电流在荧光屏上成像，并对气体暴露的响应进行了初步测量，表明空气降低了这些器件的发射率。这项工作展示了一个简单的室温过程，形成场致发射体，场致发射材料系统与导电氧化物，和初步证据表明，空气可以降低场致发射通过一个纯粹的偶极相互作用。
We report a technique for forming nanopatterned films of organic conducting composites at room temperature. The devices are formed by copying a nonlithographically produced template to form a high-aspect-ratio volcano-like structure. Field emission was studied from these structures, and they were found to provide a field enhancement of about 250. The emission current was imaged on a phosphor screen and preliminary measurements were made of the response to gas exposure, demonstrating that air decreases the emissivity of these devices. This work demonstrates a straightforward room-temperature process for forming field emitters, a field-emitting material system with a conducting oxide, and preliminary evidence that air can degrade field emission through a purely dipolar interaction.
