Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3

Tobias Schwaigert, Salva Salmani-Rezaie, Sankalpa Hazra +9

Epitaxial strain is a powerful means to engineer emergent phenomena in thin films and heterostructures. Here, we demonstrate that KTaO3, a cubic perovskite in bulk form, can be epi…
