Abstract
SrMO3 (M:Ce and Zr) thin films and SrCeO3/SrZrO3 superlattices have been made by ArF excimer laser ablation method. The structures of SrCeO3 and SrZrO3 are strongly distorted from the ideal perovskite structure. A characteristic property of these oxides is a large amount of protons can be introduced into the crystal, when acceptor (trivalent cation) ions are doped.
