abstract = {We observed significant influence of the top-electrode
material on the thickness and temperature dependences of the
dielectric response of single-crystalline Ba0.7Sr0.3TiO3
thin-film capacitors. For SrRuO3/Ba0.7Sr0.3TiO3/SrRuO3
samples, the position of dielectric maximum shifts to lower
temperatures with decreasing film thickness, whereas the
samples with Pt top electrodes exhibit an opposite trend.
Moreover, the apparent "interfacial" capacitance, extracted
from the film-thickness dependence of dielectric response,
is very different for these two types of samples and
strongly depends on temperature. Experimental results are
analyzed theoretically in light of the depolarizing-field
and strain effects on the transition temperature and
permittivity of ferroelectric films. (c) 2005 American
