(a) Grazing angle incidence X-ray diffraction patterns and (b) current versus applied voltage plots of as-deposited, 400 oC annealed and 500 oC annealed STO films on Pt/TiO2/SiO2/Si substrate. TiN and Pt layers were deposited sequentially on STO layer for top electrode in (b). The inset figure in (b) shows the URS set (compliance current: 0.5mA) and reset switching curves of the as-deposited and 500 oC annealed STO films.
