%X Two pure hexagonal phases of titanium dioxide, anatase and rutile, were grown on c-cut Al<sub style=\"font-family:\" white-space:normal;\"=\"\"><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\">O</span><sub style=\"font-family:\" white-space:normal;\"=\"\"><span style=\"font-family:Verdana;\">3</span></sub><span style=\"font-family:Verdana;\"> substrates via pulsed-laser deposition by changing only the growth and annealing conditions, but without changing the substrate, target, or working gas. Purity of each phase was confirmed by x-ray diffraction, the quality of each film was studied using atomic force microscopy and scanning electron microscopy, and the interface between each substrate and film was studied using x-ray photoelectron spectroscopy.
