Semiconducting polymers have been extensively studied for optoelectronic device applications such as organic light-emitting devices, organic solar cells, organic field-effect transistors, organic photodiodes, organic phototransistors, organic memory devices, etc. To improve the performance of these organic optoelectronic devices, the sophisticated technology that can control the bulk and/or surface nanostructures of semiconducting polymer nanolayers is utmost important. Recently we have attempted to improve the property of semiconducting polymer nanolayers by introducing novel ‘micro/nano-pressing’ technique which can enable low-cost patterning on the surface of nanolayers and eventually be applied to robust roll-to-roll processes. In this work we report the optical and electrical characteristics of semiconducting polymer nanolayers made by the micro/nano-pressing technique. Finally, we present positive effects of this technique for organic devices (transistor and solar cells). |
