The effect of dopants on the electronic structure of SnO2 thin film

In this paper, the structure of SnO2 thin films doped with Pd, Sb, Pt and In, especially the effects of dopants on the electronic structure of SnO2 were studied by XPS and TEM. It was observed that the dopants not only changed the Fermi level but also influenced the distribution of electron state density (DESD) of Sn4d valence band. We also studied the electronic structure change of the doped SnO2 after H2 adsorption.
