Size-dependent electromechanical response and ferroelectric behavior of engineered morphotropic phase boundary PbZr1−Ti O3 nano-heterostructures

An enhancement of electromechanical performance in ferroelectric materials commonly requires a delicate control of compositions to the proximity of morphotropic phase boundary. Here, we demonstrate an alternative design strategy for enhanced electromechanical responses by engineering ferroelectric PbZr1−xTixO3 nano-heterostructures, where the overall composition is near the morphotropic phase boundary yet compositions of constitutive layers are...
