Extract

Research into the growth of high-quality single crystal thin films of high transition temperature (Tc) superconductors have stimulated interest in other perovskite metal oxides with a variety of physical properties.1 Thin films of perovskite materials are among the major focal research areas for optical, sensor, electronic, and superconducting applications.1 Two lanthanumbased oxygen/electronic conducting perovskite oxides of particular interest for high temperature fuel cell electrodes and interconnects and for other electrochemical applications such as oxygen separation devices are Lal-xSrxMnO3-y and Lal-xSrxCoO3-y. The La-based perovskites are valuable for these technologies because they reduce interfacial resistances by eliminating the need for a three phase contact area (gas, metal electrode, electrolyte).2 In addition, these oxides may also serve a valuable role as novel catalysts or catalytic supports; however, little is known about what catalytic properties they may possess.
