| Research Abstract |
In order to investigate features of Dirac electron system realized both in the organic conductor, α-(BEDT-TTF)2I3, under pressure and on the surface of the topological insulator, Bi2Se3, tunneling spectroscopy techniques under magnetic fields are developed. As the results, the synthetic methods for high-quality samples of carrier-compensated Bi2Se3, and a strong candidate for a topological superconductor, Cu-intercalated Bi2Se3, and problems of tunneling spectroscopy on the above materials by the point-contact method are revealed.
