英文摘要
We have investigated the electronic state of various high-Tc cuprates such as (Y, Ca)Ba_2Cu_3O_y, by using Raman scattering, optical reflectivity and transport measurements. We found that the polarization dependence of Raman scattering that is typical for d-wave superconductors is lost when a pseudogap is closed, and that carrier overdoping induces unpaired carriers due to some mechanism different from a usual impurity pair-breaking. All these results strongly suggest that the electronic state in the overdoped regime is intrinsically inhomogeneous.
