Abstract
An investigation is made of the dependence of carrier activation energies calculated from the temperature characteristics of the thermoelectric power and the dc conductivity on the changing composition in the binary and ternary glassy systems based on As–Te. In contrast to their linear dependence on the content of Tl atoms in the ternary glassy system As2Te3 + Tlx a maximum of the activation energies at the stoichiometric composition is found in the binary glassy system Asx–Te100–x. Some ideas of White's model are used for an explanation of these concentration dependences. [Russian Text Ignored].
