Investigation of the structure of GexAsySe1−x−y glasses by x-ray photoelectron spectroscopy
We have measured and analyzed x-ray photoelectron spectra of a series of GexAsySe1−x−yglasses. The valence band spectra show that a number of Se-rich structures exist in the samples. After decomposing Ge, As, and Se3dspectra into several doublets and assigning them to the different local bond structures, it was found that, while GeSe₄/₂ tetrahedral, AsSe₃/₂ pyramidal, and Se trimers decrease in their integrated areas, most defect bonds increase with increasing mean coordination number....[Show more]
