      Anisotropy of the optical dielectric function in the ab plane for YBa2Cu3O7- 

      Kotz, A. L.; Klein, M. V.; Lee, W. C.; Giapintzakis, John; Ginsberg, D. M.; Veal, B. W. (1992)
      We report ellipsometric measurements from surfaces of three single-crystal samples of YBa2Cu3O7. Two of the samples were untwinned with Tc=90 and 66 K. The third sample was a tetragonal single crystal with low oxygen content ...

      Development of the optical conductivity with doping in single-domain YBa2Cu3O6+x 

      Cooper, S. L.; Kotz, A. L.; Karlow, M. A.; Klein, M. V.; Lee, W. C.; Giapintzakis, John; Ginsberg, D. M. (1992)
      Optical studies of single-domain crystals of YBa2Cu3O6+x allow us to separate the CuO2-plane and CuO-chain contributions to the optical conductivity as a function of doping between 0.025 and 5.5 eV. We find several interesting ...
