The charge ordered Bi(0.4)Ca(0.4)Sr(0.2)MnO(3) (BCSMO) film has been grown on (011) SrTiO(3): Nb (STON) (0.05 wt%) substrate. The charge ordering (CO) transition is realized at similar to 336 K. The BCSMO/STON heterojunction shows excellent rectifying behavior. Through the capacitance measure of the junction, it is found that the built-in potential of the heterojunction is affected by the CO transition. A upward shift of the built-in potential of the junction appears around the CO transition temperature, which is ascribed to the change of the Fermi level in BCSMO film. (C) 2010 Elsevier Ltd.
