Query: Domain enhanced interlayer coupling in ferroelectric/paraelectric
  superlattices   We investigate the ferroelectric phase transition and domain formation in a
periodic superlattice consisting of alternate ferroelectric (FE) and
paraelectric (PE) layers of nanometric thickness. We find that the polarization
domains formed in the different FE layers can interact with each other via the
PE layers. By coupling the electrostatic equations with those obtained by
minimizing the Ginzburg-Landau functional we calculate the critical temperature
of transition Tc as a function of the FE/PE superlattice wavelength and
quantitatively explain the recent experimental observation of a thickness
dependence of the ferroelectric transition temperature in KTaO3/KNbO3
strained-layer superlattices.
