摘要：

Structural control of titanium dioxide, TiO2, thin films was achieved by the selection of appropriate substrates. The rutile phase of the TiO2 thin film was grown on alpha-Al2O3(0 0 0 1) substrate, while the anatase phase was on SrTiO3(0 0 1) and LaAO(3)(0 0 1) substrates. The crystallinity of the anatase films has been much improved by the use of the LaAlO3(0 0 1) substrate. The combinatorial doping with 3d transition metals in the TiO2 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.
