Title: Microstructure and electrical properties of Na{sub 0.5}Bi{sub 0.5}(Ti{sub 0.98}Zr{sub 0.02})O{sub 3} thin film deposited on indium tin oxide/glass substrate

Highlights: • NBTZr deposited on ITO/glass under O{sub 2} exhibits a phase-pure perovskite structure. • NBTZr shows a well-defined P–E with a remanent polarization of 11.5 μC/cm{sup 2}. • At 100 kHz and 14 V, the dielectric tunability is 44.97% and FOM is 3.58. • At 100 kHz, the ϵ{sub r} and tanδ are 205 and 0.092, respectively. - Abstract: Na{sub 0.5}Bi{sub 0.5}(Ti{sub 0.98}Zr{sub 0.02})O{sub 3} (NBTZr) thin film has been prepared by chemical solution deposition onto indium tin oxide (ITO)/glass under O{sub 2} atmosphere. The microstructure and related electrical performance are investigated. The film exhibits a phase-pure polycrystalline perovskite structure, with evenly distributed grain size and full compactness. A well-defined polarization-electric field (P–E) loop can be observed with a remanent polarization (P{sub r}) of 11.5 μC/cm{sup 2} and small gap. At 14 V and 100 kHz, the dielectric tunability as high as 44.97% can be achieved and the dielectric constant of 205, dissipation factor of 0.092 as well as figure of merit of 3.58 are obtained.
