This paper describes the electronic phase diagram of Bi-based high-Tc superconductors (Bi2Sr2CaCU2O8 + δ) revealed by their transport properties. Because the normal state properties of high-Tc cuprates are hard to understand within the Fermi-liquid picture, which provides the basis for the BCS theory, studies on the normal state properties are becoming very important. We explored the underdoped properties of Bi2Sr2CaCu2O8 + δJ by growing high-quality single crystals and controlling their oxygen content precisely. Based on the results, we propose a new electronic phase diagram of the pseudogap state for high-Tc cuprates.
