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…
