Tuning the electronic structure of SrTiO3/SrFeO3−x superlattices via composition and vacancy control
Using density functional theory-based calculations, we explore the effects of oxygen vacancies and epitaxial layering on the atomic, magnetic, and electronic structure of (SrTiO3)n(SrFeO3−x)1 superlattices. While structures without oxygen vacancies (x = 0) possess small or non-existent band gaps and...
