Vapor-Liquid-Solid (VLS) growth method is a liquid-assisted vapor phase epitaxy. This method can provide high quality RE123 films at a high rate. However, there are mostly no reports that introduced nanorods as APC using this method. In this study, we suggest introducing BaHfO₃ nanorods into the VLS grown Sm123 films using solid layer with projecting upper part of nanorods, and thin liquid layer. We also report superconducting properties and the microstructure in BaHfO₃-doped VLS-Sm123 films.
