| Outline of Final Research Achievements |
Polymer semiconductor, in which conjugated organic molecules are polymerized, is an electronic material excellent in solubility, homogeneous film formation by solution processes, low temperature processability, and mechanical flexibility. However, having many structural disorders and defects, polymer semiconductor had been believed to follow hopping transport model, where the maximum mobility is at most several cm2/Vs. In this study, we have clarified that band transport can be realized in some polymer semiconductors by the measurements of mobility exceeding 10 cm2/Vs, its temperature dependence and Hall effect. The relationship between structure and band conduction was also analyzed in detail.
