· SmErO3

SmErO3 is a rare-earth oxide perovskite ceramic compound containing samarium and erbium cations. This material is primarily investigated in research and development contexts for its semiconducting and ionic-transport properties, particularly as a potential electrolyte or functional component in solid-oxide fuel cells (SOFCs) and other high-temperature electrochemical devices where rare-earth doped perovskites offer enhanced oxygen-ion or mixed-ion conductivity.
