Optical study of pseudogap state in single layer Bi{sub 2}Sr{sub 2}CuO{sub 6+{delta}}

· Journal of Low Temperature Physics
The authors present infrared reflectivity measurements of the ab-plane response of Pb- and La-doped Bi{sub 2}Sr{sub 2}CuO{sub 6+{delta}} single crystals. A suppression of scattering rate is observed for La-doped samples below and above {Tc}, suggestive of a pseudogap. Compared with double-layer Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}}, the suppression is weak and appears at lower frequencies. This may reflect a weak pairing interaction and/or smaller gap amplitude.
