| Research Abstract |
We have aimed to control the physical properties of oxide films by using photocarrier injection (PCI) method. In VO_2/TiO_2(001) system, it is found that making a sharp interface is important to control the physical properties by PCI method, because the solid solution is formed at the interface between the film and the substrate. In SnO_2 system, a large change in resistance is observed under an ultraviolet light irradiation. We have developed the materials to which we would apply the PCI method. We have successfully obtained a high quality CrO_2 thin film by developing a preparation method and also found a room temperature ferromagnetic behavior in hollandite-type Ti oxide compounds.
