How to make a thin layer of crystalline barium titanate on copper substrate?

Is it possible to create a thin [$\ce{BaTiO3}$](https://en.wikipedia.org/wiki/Barium_titanate) crystal layer on a copper plate by putting the plate in a beaker, pouring in heated [hydrofluoric acid](https://en.wikipedia.org/wiki/Hydrofluoric_acid) that has been saturated with $\ce{BaTiO3}$ powder and letting it cool?


An alternative method could be [CVD](https://en.wikipedia.org/wiki/Chemical_vapor_deposition), though it's more expensive.
