Outline of Final Research Achievements

In order to study a mechanism of electrical conductivity in the conductive polymer poly(3,4-ethylenedioxythiophene) / poly(4-styrenesulfonate) (PEDOT/PSS), measurements of low-temperature electrical resistivity and scanning tunneling microscopy (STM) have been performed in ethylene glycol added PEDOT/PSS film. The edge-casting PEDOT/PSS film shows the low resistivity ~1 mΩcm and the orientation effect with the anisotropy ~2.2. STM results indicate that the film consists of fibril microstructures (width: ~3 nm) and the conductivity increases along the fibril. On the other hand, the drop-casting film and spin-coated film show randomly oriented grain structure (20-40 nm) without any orientation effect.
