N2 - Structural control of titanium dioxide, TiO 2 , thin films was achieved by the selection of appropriate substrates. The rutile phase of the TiO 2 thin film was grown on α-Al 2 O 3 (0 0 0 1) substrate, while the anatase phase was on SrTiO 3 (0 0 1) and LaAlO 3 (0 0 1) substrates. The crystallinity of the anatase films has been much improved by the use of the LaAlO 3 (0 0 1) substrate. The combinatorial doping with 3d transition metals in the TiO 2 thin films was carried out for the rutile and anatase films in much shorter time than the conventional one-by-one process, leading to the discovery of transparent ferromagnetism in the Co-doped anatase film.
