Abstract
The results of a study of the atomic structure and crystallization behavior of As-Te glasses are reported. The primary tool of this investigation is Mössbauer-effect spectroscopy of the Te sites. Strikingly different behavior of the spectra is observed depending on whether the As content is above or below 40 at.%. In As-rich compositions, a well-defined Te site exists in which Te is twofold covalently bonded to As. For As-poor compositions, both twofold and threefold Te sites are observed. The poor glass-forming abilities of As-Te alloys (compared to As-Se or As-S) can be associated with the presence of these two types of Te environments.Keywords
