Abstract
The hole-state and defect structure of proton conductor SrTi1-xScxO3 have b een studied by high-resolution X-ray absorption spectroscopy. The proton-in duced level is observed in proton-doped SrTi1-xScxO3. The energy separation between the top of the valence band and the bottom of the acceptor or prot on level is considered to be the activation energy determined by electronic or proton conductivity.
