Abstract We present infrared reflectivity measurements of the ab-plane response of Pb- and La-doped Bi 2 Sr 2 CuO 6+δ single crystals. A suppression of scattering rate is observed for La-doped samples below and above T c , suggestive of a pseudogap. Compared with double-layer Bi 2 Sr 2 CaCu 2 O 8+δ , the suppression is weak and appears at lower frequencies. This may reflect a weak pairing interaction and/or smaller gap amplitude.
