Heterostructures composed of perovskite overlayers on anatase TiO2 films were fabricated on LaAlO3 substrates. By depositing LaTiO3 and LaAlO3 thin films on the insulating anatase TiO2 films, metallic conduction was induced in the anatase layer with the increasing thickness of the perovskite overlayer. This perovskite overlayer deposition on TiO2 provides a method to induce free carriers, which may be applied to the development of transparent conducting oxides.

    Titanium oxide thin films were prepared by pulsed-laser deposition on LaAlO3 single crystal substrate at 700 °C. Pure anatase films are obtained at high oxygen pressure (10-1 mbar), while the rutile phase is evidenced at low oxygen pressure (10-5 mbar) despite a large oxygen deficiency...
