Oxygen vacancy-induced structural evolution of SrFeO epitaxial thin film from brownmillerite to perovskite
Seulki Roh, Seokbae Lee, Myounghoon Lee +8
We investigated SrFeO thin films on a SrTiO (001) substrate prepared via pulsed laser epitaxy using an optical spectroscopy technique. The oxygen vacancy level () wa…
