Effect of the thickness of Sr2Bi4Ti5O18 transition layer on the properties of BiFeO3/Sr2Bi4Ti5O18 bilayer composite thin films

Modulating light absorption and multiferroic properties of BiFeO3-based ferroelectric films by the introduction of ZnO layer

“…On the contrary, the leakage current densities of ZnO/BFO and BFO/ZnO bilayers were found to be lower than that of the BFO thin film. As the ZnO layer was added, a prominent decrease in the leakage current density was observed, which can be put down to the movement blocking of the oxygen vacancies and electrons of the ZnO layer which acted as an efficient insulator between BFO and the Pt substrates and electrodes [32]. In addition, the reducing the leakage current density may be caused by a potential barrier formed at the interface between BFO and ZnO, which blocked the conduction of carriers in the composite films [33].…”

Effect of ZnSnO3 on dielectric and ferroelectric properties of Sr2Bi4Ti5O18 ceramics

“…As a result, ferroelectric solid solutions in bulk configuration and heterostructures in thin-film configuration always perform better overcoming the drawbacks of individual constituents for practical device applications. 4,5 Ferroelectric solid solutions have gained unprecedented importance for dielectric, piezoelectric, and ferroelectric applications owing to their superior physical properties compared to individual ferroelectric electro-ceramic material systems. However, the choice of high-performance ferroelectric solid solutions has been strictly limited to very few material compositions either due to a lack of rigorous research investigations or material-specific limitations.…”

“…Despite several decades of research effort, there is no unique ferroelectric material system suitable for all possible ferroelectric devices due to their associated merits and demerits. As a result, ferroelectric solid solutions in bulk configuration and heterostructures in thin‐film configuration always perform better overcoming the drawbacks of individual constituents for practical device applications 4,5 . Ferroelectric solid solutions have gained unprecedented importance for dielectric, piezoelectric, and ferroelectric applications owing to their superior physical properties compared to individual ferroelectric electro‐ceramic material systems.…”
