Abstract

The temperature dependent infrared conductivities of Bi₂Sr₂CaCu₂O₈ (T_c {reversed tilde equals} 82 K) and Bi₂Sr₂CuO₆ (T_c {less-than or approximate} 5 K) are compared with non-Fermi liquid approaches to the normal state of the high T_c superconductors. We find reasonable agreement with our data only for ω {less-than or approximate} 0.12 eV. We attribute the remaining spectral weight to a low-energy excitation in copper-oxide superconductors doped well above the metal-insulator transition.
