Photoemission (XPS and UPS) study of amorphous Bi
1984年8月1日 · In this study we performed an XPS measurement for amorphous BizSe3, a prototype of Bi-doped chalcogenide glasses, paying special attention to the chemical shift of the core levels of the two components.
The present XPS results indicate that Bi enters the Ge–S matrix as a positively charged center. This observation lend support to the mechanism which proposes that Bi is incorporated as a positive charged center, upsetting the equilibrium between native charged defect centers and causing the p–n switch-ing.
