A porous hybrid of titanate nanosheets with SnO(2) nanoparticles has been realized by an exfoliation and reassembling route. The present nanohybrid shows a large reversible capacity of 860 mA h g(-1) with a good capacity retention (about 60% retention of the initial capacity after 50 cycles).

The functional properties of two types of barium strontium titanate ~BST! thin film capacitor structures were studied: one set of structures was made using pulsed-laser deposition ~PLD! and the other using chemical solution deposition. While initial observations on PLD films looking at the behavior of Tm ~the temperature at which the maximum dielectric constant was observed! and Tc* ~from Curie...

Ba0.5Sr0.5TiO3 ~BST! thin films grown on Si by an in situ ultraviolet-assisted pulsed laser deposition ~UVPLD! technique exhibited significantly higher dielectric constant and refractive index values and lower leakage current densities than films grown by conventional PLD under similar conditions. X-ray photoelectron spectroscopy ~XPS! investigations have shown that the surface layer of the gro...
