dc.description.abstract | 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. Moreover, while the appearance of Se trimers is reasonable in Se-rich samples, they never vanish, even in Se-poor samples. A possible mechanism to form Se trimers in Se-poor samples is discussed. | |
