Tóm tắt

Thin films of Zr/sub 1-x/Sn/sub x/TiO/sub 4/ (ZTS) were prepared by the polymeric precursor route. The influence of process parameters and dopants (Nb, Sb and Ta) on the chemical composition of the films was investigated by means of the XPS technique. Surface segregation of Sn/sup IV/ and the presence of Sn/sup 0/, Ti/sup II/, and Ti/sup III/ species in the films were revealed from XPS depth profiles.
