概要
- 論文の詳細を見る
The Ce–O hybridization effect of protonic conductor Y3+-doped SrCeO3 (SrCe1-xYxO3-δ) has been studied by resonant-photoemission spectroscopy (RPES). The RPES spectra show that the Ce $4f$ partial density of states in the valence band increases with increasing Y3+ dopant concentration. This finding indicates that the hybridization effect between the Ce $4f$ and O $2p$ states increases with Y3+ dopant concentration.
