Abstract
According to the assumption that the glass formation in tetrahedrally bonded multicomponent glasses is due to chains of the V group elements, glasses in the (Cd, GeAs, )l–x, (TIAs)x, system are obtained. The transformation of the main structure type of glass (from tetrahedrally bonded into arsenic) together with the change of its properties is shown. The differences in the properties of the glasses is markedly revealed during hydrostatic pressure experiments and during the study of the temperature dependence of thermoelectric power. These differences are probably connected with the change of the coordination number of As to 3 in arsenic glasses and are in agreement with the valence alternation pair model. The obtained glasses according to the results of thermoelectrical measurements are semiconductors of n-type with rather high conductivity (up to f2−1 ω−1 at room temperature). [Russian Text Ignored].
