摘要: High‐performance film dielectrics are crucial for capacitive energy storage applications and electronic industries. In this work, improvements of dielectric and energy performance in BiFeO3‐based films are realized by constructing sandwich architectures, which integrates complementary features of spatially organized dielectric layers in a synergistic manner to realize concurrently high permittivity/polarization and low loss/leakage. Moreover, by rationally modifying the sandwich configuration, ie, with insulating layers on the outside, the …
