Highly Oriented SrTiO3 Thin Film on Graphene Substrate

Year: 2017

Type: article

Abstract: Growth of perovskite oxide thin films on Si in crystalline form has long been a critical obstacle for the integration of multifunctional oxides into Si-based technologies. In this study, we propose pulsed laser deposition of a crystalline SrTiO 3 thin film on a Si using graphene substrate. The SrTiO 3 thin film on graphene has a highly (00 l )-oriented crystalline structure which results from the partial epitaxy. Moreover, graphene promotes a sharp interface by highly suppressing the chemical intermixing. The important role of graphene as a 2D substrate and diffusion barrier allows the expansion of device applications based on functional complex oxides.
