Abstract
The measurement of d.c. electrical conductivity of the bulk samples of chal cogenide glasses of the system Ge10+xSe40Te50-x (x = 0.0, 13.35, 16.65 at.% ) are studied. The activation energies are obtained from conductivity measu rements, using Mott and Davis equation. The relationship between the energy of decomposition Ed and composition is discussed in terms of the average h eat of atomization. The effect of heat treatment on the structure transform ation is investigated by X-ray diffraction and scanning electron microscope . (C) 2000 Elsevier Science S.A. All rights reserved.
