Abstract

n- and p-type doping of MgO are induced in contact with Fe^IFe^II and (Fe^II)₂N terminations of Fe₄N, respectively. The metallic characteristics are induced in BaTiO₃ by contact with Fe^IFe^II termination, whereas p- and n-type doping appears in (Fe^II)₂N/BaO and (Fe^II)₂N/TiO₂ interfaces, respectively. The interfacial dipole due to charge rearrangement may induce the Fermi level pinning in Fe₄N/MgO and (Fe^II)₂N/BaTiO₃ interfaces. The deposition of Fe₄N on BiFeO₃ can result in a metallic BiFeO₃.
