Within the kinetic energy driven superconducting mechanism, we study the superconducting quasiparticle spectral weight of cuprate superconductors. It is shown that although the spectral weight is continuous along the high symmetry directions, the overall spectral weight is reduced by the strong electron correlation in cuprate superconductors.

AbstractCharge-transfer salts of EDT-TTF with tetrahedral anions MX4 (M=Fe, Ga ; X=Cl, Br) were prepared. They are isostructural to each other (monoclinic P21/m) with the stoichiometry of 2:1. All of them are semiconductors having the conductivity at room temperature of 5 to 9 Scm−1 and activation energy of 40 to 170 meV. Since the calculated band structure of them indicate that they should be quasi one-dimensional metals, they were discussed from the point of structural deformation and strong electron correlation.
