Physicochemical properties of proton-conducting SmNiO3 epitaxial films

Journal of Materiomics, 2019
Proton conducting SmNiO3 (SNO) thin films were grown on (001) LaAlO3 substrates for systematically investigating the proton transport properties. X-ray Diffraction and Atomic Force Microscopy studies reveal that the as-grown SNO thin films have good ...
