Ferrite perovskites have exhibited promising p-type conductivity and oxygen evolution reaction (OER) activity. In this work, we investigate heteroepitaxial p-n junctions formed by La0.88Sr0.12FeO3 and n-SrTiO3(001). Sr substitution for La in LaFeO3 is shown to be effective for introducing p-type con...
