講座內(nèi)容：In this talk, Prof. Kubozono will introduce Research Institute for Interdisciplinary Science, Okayama University,and recent work about superconductors based on two-dimensional layeredmaterial. His group is working on design and characterization of superconductors fabricated by electron-doping of two-dimensional layered materials. New super conductors are particularly fabricated using techniques ofmetal-doping and electrostatic electron doping. Furthermore, they have investigated physical properties of super conductors under pressure. The super conductivity of metal-doped materials of FeSe_1-zTe_z,Bi₂Se₃(topological insulator), and graphite, black phosphorus as well as electrostatic electron-doped LaOBiS₂will betalked in this lecture. The pressure-driven super conductivity is also topic of this lecture, in which they have achieved 50 K super conductivity.
