Study of highly correlated electron system by angle resolved thermoelectric power measurement, using Corbino disk-type temperature gradient

我们的目标是开发一种新的方法，使我们能够测量角分辨的热电功率准连续的，在高度相关的电子系统中的电子各向异性的重要性的动机。起初我们把这种方法应用于有机导体。此外，我们还尝试建立了确定费米面各向异性的新方法，研究了绝缘相附近金属态的反常输运性质，并确定了超导电性的对称性。实际上，我们成功地观察到了有机材料的角相关热电势，这反映了费米面的各向异性。

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.
