Abstract
The short range order structure of Bi13Ge20Se67-xTex glasses (x = 0, 5, 10, 15, 20 at.%) is explored by using high-resolution X-ray photoelectron spectroscopy. Results show that the incorporated oxygen from surface containment of specimens and Te substitution for Se exert important impacts on the network structure of glasses. Oxygen breaks the GeGe homopolar bonds in the GeSeBi glass, leading to a significant reduction of the over-constrained GeGe(Se)3 ethane-like units. Te addtion promotes the formation of mixed BiSe(Te)3/2 nanolayers as crystal precursors, thus initiating crystallinzation in competition to a topological self-organization process. The present work will be helpful to deepen the understanding of ChG glasses for applications in fields of optoelectronics and photonics.
