Abstract

The hole-state and defect structure of proton conductor SrTi_1-xSc_xO₃ have been studied by high-resolution X-ray absorption spectroscopy. The proton-induced level is observed in proton-doped SrTi_1-xSc_xO₃. The energy separation between the top of the valence band and the bottom of the acceptor or proton level is considered to be the activation energy determined by electronic or proton conductivity.
