Optical Response of High-Dielectric-Constant Perovskite-Related Oxide
TL;DR: Optical conductivity measurements on the perovskite-related oxide CaCu3Ti4O12 provide a hint of the physics underlying the observed giant dielectric effect in this material, suggesting the presence of a strong absorption at very low frequencies due to dipole relaxation.
Journal ArticleDOI
Optical conductivity of c axis oriented YBa2Cu3O6.70: Evidence for a pseudogap.
TL;DR: The c axis reflectance of high-quality single crystals of YBa 2 Cu 3 O 6-x has been measured over a wide range of temperatures and frequencies and observations are consistent with phase diagrams proposed to explain NMR and neutron data.
Journal ArticleDOI
First-principles study of the structure and lattice dielectric response of CaCu 3 Ti 4 O 12
TL;DR: In this article, the structural and electronic properties of the zone-center optical phonon frequencies were evaluated using the frozen-phonon method and mode effective charges were determined from computed Berry-phase polarizations.
Journal ArticleDOI
Technique for measuring the reflectance of irregular, submillimeter-sized samples
TL;DR: Details are given of a technique for measuring the reflectance at near-normal incidence of small, irregular, submillimeter-sized samples by using a modified Michelson interferometer or grating spectrometer.

TL;DR: In this paper, the scaling relation of the superfluid density with the superconducting transition temperature (T(c) was shown to hold regardless of doping level, nature of dopant (electrons versus holes), crystal structure and type of disorder, and direction.
