Carrier relaxation time divergence in single and double layer cuprates (2007)
Schneider, ML, Rast, S, Onellion, M, Demsar, J, Taylor, AJ, Glinka, Y, ...
We report the transient optical pump-probe reflectivity measurements on single and double layer cuprate single crystals and thin films of ten different stoichiometries. We find that with sufficiently...
Park, S., Kang, K., Si, W., Yoon, W. -S., Lee, Y., Moodenbaugh, A. R., ...
We have prepared the oxyhydrate Na03RhO206H2O by extracting Na+ cations from NaRhO2 and intercalating water molecules using an aqueous solution of Na2S2O8. Synchrotron X-ray powder diffraction,...
Synthesis and Structure of the Monolayer Hydrate K03CoO2 x 04H2O (2005)
Park, S., Lee, Y., Si, W., Vogt, T.
The monolayer hydrate (MLH) K03CoO2 x 04H2O was synthesized from K06CoO2 by extracting K+ cations using K2S2O8 as an oxidant and the subsequent intercalation of water between the layers of...
Charge transfer in the high dielectric constant materials CaCu3Ti4O12 and CdCu3Ti4O12 (2002)
Homes, C. C., Vogt, T., Shapiro, S. M., Si, W., Wakimoto, S., Subramanian, M. A.
The cubic perovskite-related ceramic CaCu3Ti4O12 has a very high static dielectric constant ~10000 at room temperature (RT), which drops to about 100 below about 100 K. Substituting Cd for Ca reduces...
Si, W., Cruz, E. M., Johnson, P. D., Barnes, P. W., Woodward, P., Ramirez, A. P.
Pulsed-laser deposition has been used to grow epitaxial thin films of the giant-dielectric-constant material CaCu_3Ti_4O_{12} on LaAlO_3 and SrTiO_3 substrates with or without various conducting...
