摘要：

The proton conduction of Se-doped SrTiO3 (SrTi1-xScxO3) has been studied in the single crystal form. The SrTi1-xScxO3 crystals exhibit significantly higher conductivities than the pure ones, and the crystal with x = 0.02 exhibits sufficiently higher conductivity than any other. The activation energy of SrTi1-xScxO3 crystals decreases rapidly with increasing Sc3concentration at x less than or equal to 0.02, then increases slightly when x greater than or equal to 0.02. These results indicate that the protonic conduction of SrTi1-xScxO3 depends on the Sc3+ dopant concentration.
