| Abstract | The ab-plane optical properties of the high-temperature superconductor Bi 2Sr2CaCu2O8 are anisotropic in both the normal and the superconducting state. Consistent with the orthorhombic structure, the principal axes lie along thea and b crystallographic axes, nearly 45° from the Cu-O bond direction. In the normal state, analysis of the temperature-dependent optical conductivity suggests a scattering rate for the free carriers that showsab anisotropy in both magnitude and temperature dependence. In the superconducting state, the anisotropy in the oscillator strength of the superfluid response determined from the far-infrared frequency dependence ofs2(v) and from a sum-rule analysis leads to a penetration depth lD t at is larger along the b axis than the a axis: (lL .lL ). @S0163-1829 ~99!01845-7# |
