- Abstract
A ferroelectric/multiferroic structure composed of (PbSr)TiO (PST) and (BiLa)FeO (BLF) was heteroepitaxially deposited on a LaNiO buffered (001) SrTiO substrate by pulse laser deposition. Interestingly, the PST layer was acting as a buffering layer between BLF and electrode to suppress the migration of free carries in the heterostructure. A well-grown crystalline dense structure was observed from the surface morphology of PST/BLF/PST heterostructure. Moreover, the PST/BLF/PST trilayer exhibited improved ferroelectric and dielectric behaviors, together with two orders of magnitude lower leakage current and higher dielectric constant. Our result indicate that the multiferroic PST/BLF/PST heterostructure may have a promising application for the future high-density memory.
