Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO 3

ABSTRACT Epitaxial strain is a powerful means to engineer emergent phenomena in thin films and heterostructures. Here, we demonstrate that , a cubic perovskite in bulk form, can be epitaxially strained into a highly tunable ferroelectric. films grown commensurate to (001) substra...
