| Research Abstract |
We aimed to develop the novel method that enable us to measure angle-resolved thermoelectric power quasi-continuously, motivated by the importance of electronic anisotropy in highly correlated electron system. At the beginning we applied this method to organic conductors. Moreover we tried to construct novel method of determining Fermi surface anisotropy, studying anomalous transport properties of metallic state near insulating phase and determining symmetry of superconductivity. Indeed we succeeded in observing angle-dependent thermoelectric power of organic materials, which reflect anisotropy of Fermi surface.
