abstract = {Thin films of (BaxSr1-x)TiO3 were deposited on Pt-coated Si
substrates by chemical solution deposition. The films were
postannealed under ozone atmosphere at various temperatures.
Although there was no change observed in the microstructure
after the anneal in ozone, the dielectric dispersion and the
loss tangents were reduced for the films. It was also
noticed that the leakage current reduced by almost two
orders of magnitude after treatment with ozone. The ozone
treatment was done at various temperatures between 250 and
450 degrees C to find an optimum temperature with regard to
the electrical properties. Films postannealed in ozone at
350 degrees C for 30 min showed a leakage reduction by
almost three orders of magnitude. The leakage dependence on
ozone postannealing is discussed on the basis of an
interface-dominated (Schottky injection) and a
bulk-dominated (point defect approach) charge transport
process as the two limiting conduction mechanisms across
thin films. (C) 2005 American Institute of Physics.},
