Structural ordering in Ag-based ternary chalcogenide glasses

Accepted: 15 July 1997
Results obtained by the method of isotopic substitution in neutron diffraction on the structural ordering in the glassy semiconductor show that the short-range order of the network former is retained and the Ag-Ag intermediate-range order is similar to that of the crystalline network modifier (). By comparison with results for the glassy fast-ion conductor it is concluded that silver nearest-neighbour interactions are responsible for the absence of cationic motion.
