Results obtained by the method of isotopic substitution in neutron diffraction on the structural ordering in the glassy semiconductor g-(Ag2Te)0.5(As2Te3)0.5 show that the short-range order of the network former (g-As2Te3) is retained and the Ag-Ag intermediate-range order is similar to that of the crystalline network modifier (c-Ag2Te). By comparison with results for the glassy fast-ion conductor g-(Ag2Se)0.25(AsSe)0.75 it is concluded that silver nearest-neighbour interactions are responsible for the absence of cationic motion.
