Abstract
The electronic structure in the band-gap region of protonic conductor SrZr0.90Y0.10O3-δ was studied by soft-X-ray absorption spectroscopy (XAS). The O 1s XAS spectrum of air-annealed SrZr0.90Y0.10O3-δ exhibits three distinct features, namely, the holes on top of the valence band, acceptor-induced level just above the Fermi level and Zr 4d defect-induced level at the bottom of the conduction band, which are lower in the O 1s XAS spectrum of wet-annealed SrZr0.90Y0.10O3-δ. These findings directly indicate that the doped hydrogen compensates the presence of the holes.
