| Outline of Final Research Achievements |
Cuprate superconductors are intriguing materials which show one of the most high-Tc superconducting transition temperature (Tc) in the history of superconductivity. In order to understand the mechanism of the high-Tc superconductivity, a lot of extensive studies have been demonstrated; however, it has been unclear yet. We have performed an angle-resolved photoemission study to understand the electronic structure of Bi2Sr2Ca2Cu3O10+delta (Bi2223) which has three CuO2 planes and show the one of the most highest Tc among cuprates. We have successfully observed a new band dispersion probably due to the interaction between two outer CuO2 planes. The present result indicates that the interaction between outer CuO2 planes plays an important role of the mechanism in the high-Tc superconductivity. I also have studied lattice dynamics of a multiorbital material using ultrafast electron diffraction.
