Query: Tuning of the depolarization field and nanodomain structure in
  ferroelectric thin films   The screening efficiency of a metal-ferroelectric interface plays a critical
role in determining the polarization stability and hence the functional
properties of ferroelectric thin films. Imperfect screening leads to strong
depolarization fields that reduce the spontaneous polarization or drive the
formation of ferroelectric domains. We demonstrate that by modifying the
screening at the metal-ferroelectric interface through insertion of ultrathin
dielectric spacers, the strength of the depolarization field can be tuned and
thus used to control the formation of nanoscale domains. Using piezoresponse
force microscopy, we follow the evolution of the domain configurations as well
as polarization stability as a function of depolarization field strength.
