abstract = {The equilibrium polarization states and physical properties
of single-domain Pb(Zr1-xTix)O-3 (PZT) thin films
epitaxially grown on dissimilar cubic substrates have been
examined by a nonlinear thermodynamic theory. In contrast to
the former theoretical studies of PZT films, the
two-dimensional straining and clamping of a film by a thick
substrate is correctly taken into account in the reported
calculations. The "misfit strain-temperature" phase diagrams
are developed for PZT films of several different
compositions (x=0.9, 0.8, 0.7, 0.6, 0.5, and 0.4). The
characteristic feature of these diagrams is the presence of
a "monoclinic gap" separating the stability ranges of the
tetragonal out-of-plane and the orthorhombic in-plane
polarization states. It is found that this gap widens with
the increase of Zr content, and its center shifts from
positive values of the misfit strain towards zero. The
dependences of the polarization components on the misfit
strain and composition at the room temperature are
calculated and compared with the available experimental
data. The small-signal dielectric and piezoelectric
responses of single-domain PZT films are also determined,
and their misfit-strain dependence is discussed.},
