Research Abstract |
The conduction mechanism of organic devices depends on not only organic semiconductor but also the molecular orientation. In the research we prepare the micro-structured substrates which have groove structure with width of several micro-meter. We observed NEXAFS spectra of the PTFE (polytetrafluoroethylene) film on this micro-structured substrate. From the results of NEXAFS spectra we can show that PTFE molecules have uniaxial molecular orientation where the C-C axis of PTFE is parallel to the groove direction. It is found that pentacene thin films on the uniaxially oriented PTFE substrate have anisotropic orientation by angle-resolved ultraviolet photoelectron spectra. Furthermore, we found that highly anisotropic orientation is achieved by using the substrate with highly ordered groove structure with width of several hundreds nanometer.
