Abstract

begin{wrapfigure}{r}{0pt}_x000d_ includegraphics[scale=0.9]{ISMS 2017 Abstract2.eps}_x000d_ end{wrapfigure}_x000d_ Cerium oxide is known for its use in solid oxide fuel cells due to its high ionic conductivity. The doping of trivalent samarium atoms into cerium oxide is known to enhance the ionic conductivity through the generation of additional oxygen vacancies. This study probes the electronic structure of Sm$_{x}$Ce$_{y}$O$_{z}$ ({it x}+{it y}=3, {it z}=2-4) anion and neutral clusters. Anion photoelectron spectra of these mixed metal clusters exhibit additional spectral features not present in the previously studied cerium oxide clusters. Density functional theory calculations have been used to aid interpretation of collected spectra. The results of this work can be used to inform the design of materials used for solid oxide fuel cells.
