Abstract

We present optical reflectivity and Raman scattering studies of YBa₂Cu₃O_6+x as a function of doping using c-axis polarized light. The c-axis optical response of YBa₂Cu₃O₇ is characterized by a Drude-like conductivity and an electronic Raman continuum, indicating a weak coupling between adjacent CuO₂ bilayers which is mediated by the CuO chains. With reduced doping, the c-axis Drude and continuum responses rapidly decrease, revealing a strong sensitivity of the interbilayer coupling strength to the removal of oxygen from the chain sites. We suggest that interbilayer charge transport in YBa₂Cu₃O_6+x may be governed by carrier scattering from in-plane fluctuations.
