摘要：

We report on infrared reflectivity measurements of the ab-plane response of superconducting Bi2Sr2CuO6 single crystals. The frequency-dependent conductivity has a maximum near 500 cm(-1) at room temperature, which shifts to lower frequency and merges with a Drude peak below 100 K. We attribute the unusual behavior of the midinfrared conductivity to low-frequency transitions between electronic bands of mainly BiO character near the (M) over bar point. The linear temperature dependence of the low-frequency resistivity can be followed down to approximately 40 K where it saturates.
