Abstract
Chemical solution deposition (CSD) approach was introduced in this work to simplify and to optimize the trifluoracetic based M TiO 3 ( M TO, M = Ca, Sr, and Ba) precursor solution, leading to the high shelf-life and the purity. Growing these M TO solutions on (100) LaAlO 3 single-crystal substrates yields (h00) oriented and dense M TO buffer layers. Whereas it is clear that the roughness of M TO films and the lattice mismatch between M TO buffer layer and superconducting YBa 2 Cu 3 O 7-δ film is crucial for the film formation.
