Abstract

Read online

Future technologies based on ferroelectric materials will require new routes to control the nature of polar order. Through a combined experimental and theoretical study of compositionally and strain-graded Ba1-xSrxTiO3 heterostructures, Damodaranet al. demonstrate the ability to engineer large polarization gradients and temperature-stable susceptibilities.
