Chalcogenide glass covalent bond

In complex chalcogenide glasses containing more than one chalcogen, such as in As2(Se,Te)3 it is intuitively obvious that the first heterolytic scission would occur on the weaker As-chalcogen bond so that Cr defect is formed on Te and recovery of the covalent bond would be by the coordination to Se. In this process, a relatively weaker As-Te bond is replaced by a stronger As-Se bond (see scheme below). The net energy... [Pg.343]
