It is found that mechanical force can induce an antiferroelectric/ferroelectric phase transition within micrometers of the surface. Such a phase transition is strongly dependent on the processing scenario, leading to differences from the bulk region. This work provides crucial insights into the sensitivity of this class of AFE materials. Clearly, surface processing conditions must be taken into account for both accurate structural determination and practical applications.T.L., D.C., Y.L., and R.L.W. thank the Australian Research Council (ARC) for financial support from in the form of a joint ARC Discovery Project.
