| Outline of Final Research Achievements |
The purpose of this study is to explore the possibility of device application greatly exceeding conventional performance by controlling nano-structuring and orientation of functional organic materials by using nano-lithography. We optimized etching and residual film removal process for fabrication of nanopattern of SiO 2 which is important for nanostructuring. We tried to fabricate nanostructures by graphoepitaxy for fabricationg organic nanostructures.
As a result, we succeeded in fabricating anomalous one-dimensional nanowires (NWs) in thienoacene derivatives (C8 - BTBT). A typical NW had a high aspect ratio of 15 nm in thickness, 100 nm in width, 100 μm in length. We also succeeded in forming an array structure of NWs along the nanostructure of the substrate. It has width controllability from 500 nm to 100 nm, suggesting high device application possibility.
