dc.description.abstractBased on the locality principle of insulating superlattices, we apply the method of Wu to the piezoelectric strains of individual layers under a fixed displacement field. For a superlattice of arbitrary stacking sequence, an accurate model is acquired for predicting piezoelectricity. By applying the model in the superlattices where ferroelectric and antiferrodistortive modes are in competition, functional piezoelectricity can be achieved. A strong nonlinear effect is observed and can be further engineered in the PbTiO 3/SrTiO3 superlattice, and an interface enhancement of piezoelectricity is found in the BaTiO3/CaTiO3 superlattice. © 2012 American Physical Society.
