摘要
Based on the model proposed by Kamimura and Suwa which bears important characteristics born from the interplay of Jahn-Teller Physics and Mott Physics, it is shown that the feature of Fermi surfaces is the Fermi pockets constructed by doped holes under the coexistence of a metallic state and of the local antiferromagnetic order. Then it is discussed that the phonon-involved mechanism based on the Kamimura-Suwamodel leads to the d-wave superconductivity. Further it is shown that T-c is higher in the cuprates with CuO5 pyramid than those with CuO6 octahedron. Finally a new phase diagram for underdoped cuprates is proposed.
