The effect of copper in AsSeyIz (for y = 1.4, z = 0.2) on physical and
electrical properties has been examined. Temperature dependence of th
e electrical conductivity has also been determined. Conduction type an
d activation energies of electrical conductivity have been determined
for Cu-x(AsSe1.4I0.2)(100-x) glasses, The study has also been concerne
d with spectral distribution of photoconductivity of bulk glass sample
s and thin films of analogous composition and with the determination o
f photosensitivity maxima. (C) 1998 Elsevier Science B.V. All rights r
