Ferroelectric Metal in Tetragonal BiCoO(3)/BiFeO(3) Bilayers and Its Electric Field Effect
By first-principles calculations we investigate the electronic structure of tetragonal BiCoO(3)/BiFeO(3) bilayers with different terminations. The multiferroic insulator BiCoO(3) and BiFeO(3) transform into metal in all of three models. Particularly, energetically favored model CoO(2)-BiO exhibits f...
