AbstractArtificial ferroelectric superlattices have received considerable attention because of the potential to realize macro-performance adjustments and bring exotic phenomena. In recent years, it has been reported that metallic SrRuO3 with single-unit-cell thickness can be used as the constituent material of ferroelectric superlattices, but the effect of SrRuO3 thickness on ferroelectric properties is not clear. In this study, Pb(Zr0.52Ti0.48)O-3/SrRuO3 (PZT/SRO) ferroelectric/metallic superlattices with the thickness of SRO layers ranging from 1 to 3 unit cells have been grown on Nb:SrTiO3 substrates by pulsed laser deposition (PLD), and their structural and electrical properties are investigated. The experimental results show that the electrical properties of the PZT/SRO superlattices are greatly affected by the thickness of SRO layers, and the PZT(10)/SRO2 superlattice possesses the best electrical properties. The X-ray photoelectron spectroscopy (XPS) results show that oxygen vacancies are accumulated at the PZT/SRO interfaces, which can reduce the depolarization fields and the leakage current. The results demonstrate that the thickness of metallic conducive oxide in the ferroelectric/metallic superlattices is a key factor affecting their ferroelectric properties.
