Title: Large-scale synthesis of Ba{sub x}Sr{sub 1−x}TiO{sub 3} nanowires with controlled stoichiometry

This study demonstrates a highly efficient method for large-scale synthesis BaTiO{sub 3} nanowires (NWs) using a two-step hydrothermal reaction. This synthesis process provides a facile approach to the growth of BaTiO{sub 3} NWs with high yield and control over the stoichiometry of the Ba{sub x}Sr{sub 1−x}TiO{sub 3} solid solution. The ferroelectricity of the BaTiO{sub 3} NWs is directly characterized using atomic force microscopy with the piezoelectric strain coupling coefficient (d{sub 33}) reaching 31.1 pm/V. This work provide an avenue for high volume manufacturing of ferroelectric NWs, allowing both fundamental investigation of nanoscale ferroelectricity as well as their future application in the electrical devices.
