Ideal barriers to polarization reversal and domain-wall motion in strained ferroelectric thin films

S. P. Beckman, Xinjie Wang, Karin M. Rabe +1

The ideal intrinsic barriers to domain switching in c-phase PbTiO_3 (PTO), PbZrO_3 (PZO), and PbZr_{1-x}Ti_xO_3 (PZT) are investigated via first-principles computational methods. T…
