Abstract
- The temperature dependent infrared conductivities of Bi2Sr2CaCu2O8 (Tc ⋍ 82 K) and Bi2Sr2CuO6 (Tc ⪅ 5 K) are compared with non-Fermi liquid approaches to the normal state of the high Tc superconductors. We find reasonable agreement with our data only for ω ⪅ 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.
