This substrate temperature is the lowest reported temperature for the growth of epitaxial BaTiO₃ films by an MOCVD process. The films had a cube–cube orientation relationship with the substrate and were oriented with an a-axis perpendicular to the substrate plane. Nanoscale energy dispersive x-ray spectrometry measurements showed no evidence of interdiffusion between the film and substrate
