| Abstract | Ferroelectric domain structures of epitaxial BiFeO3 thin films on miscut (001) SrTiO3 substrates have been studied by transmission electron microscopy. BiFeO3 on 0.8° miscut substrates are composed of both 109° and 71° domains; in contrast, only 71° stripe domains are observed in BiFeO3 on 4° miscut (001) SrTiO3 substrates. The domain width in BiFeO3 on 4° miscut substrates increases as film thickness increases due to a reduction in domain wall energy. The domain configurations of BiFeO3 thin films affect their ferroelectric switching behavior due to the pinning at the junctions between 109° and 71° domain walls. |
