(a) Schematic diagram of Pt/BTO:Sm2O3/Nb-STO vertical sandwich capacitors. (b) The expanded view of the dashed part in the schematic diagram to show the interfaces between Sm2O3 nanocolumns and BTO matrix. E and blue lines represent the electric field and the pathway of movement of VOs, respectively.
