Popis: 180° domain wall motion in a tetragonal ferroelectric oxide is accelerated by an order of magnitude using in situ strain in a force microscope. Single-domain PbZr0.2 Ti0.8 O3 films on piezoelectric (001)-oriented 0.72PbMg1/3 Nb2/3 O3 -0.28PbTiO3 substrates allow for direct investigation of strain-dependent domain dynamics. The strain effect depends on the sign of applied field through strain-dependent electrode built-in potentials and a suggested charging of tilted walls.
