“…B ismuth layer‐structured ferroelectrics (BLSFs) 1 have attracted a great deal of attention because of their applications to piezoelectric devices 2–9 and nonvolatile memories 10–13 . Compared with perovskite ferroelectrics such as BaTiO 3 and Pb(Ti,Zr)O 3 , BLSFs have a high Curie temperature ( T C ), which enables us to achieve the piezoelectric sensors and actuators operating at higher temperatures 14–19 .…”

Single crystals of superlattice‐structured ferroelectrics composed of Bi4Ti3O12 and PbBi4Ti4O15 were grown and the properties of polarization hysteresis and leakage current along the a‐axis were investigated. Oxidation treatment led to a marked increase in leakage current at room temperature, showing that electron hole acts as a detrimental carrier for electrical conduction. A well‐developed polarization hysteresis with a remanent polarization of 41 μC/cm2 was observed, which is suggested to originate from the peculiar ferroelectric displacement of Bi in the Bi2O2 layers.
