Outline of Final Research Achievements

New processes for oriented oxide films/structures by using photo-assisted chemical solution deposition have been developed. The applicable materials such as Ruddlesden-popper phase, CeO2, LixVO2 have also discovered. Moreover, an epitaxial strain effect of perovskite manganites from the oriented seed layer has been studied, and showed the possibility of applications of these oriented seed layers instead of single crystal substrates. High photocurrent in the photoelecrochemical water splitting in oriented multilayer photoanodes has been also shown. Thus, I have successfully shown the benefits of straightforward process for oriented oxide films.
