Abstract
PNP-type heterostructured films of P-type Na<sub>0.5</sub>Bi<sub>3.25</sub>La<sub>1.25</sub>Ti<sub>4</sub>O<sub>15</sub> and N-type BaBi<sub>3.4</sub>Pr<sub>0.6</sub>Ti<sub>4</sub>O<sub>15</sub> layers with the same Aurivillius layered perovskite structure are designed to regulate the energy storage performances by depletion region engineering.
