Mm. Elocker et al., EFFECT OF IN ADDITION ON SOME PHYSICAL-PROPERTIES OF THE AS2SE3 AMORPHOUS SYSTEM, Applied physics A: Materials science & processing, 60(2), 1995, pp. 233-238
The effect of In content on dc electrical conductivity and DTA of the
system (As2Se3)(1-x) In-x, x=0, 0.01, 0.05, has been studied. The elec
trical energy gap was found to increase for an In content 0.01% and de
crease for an In content 0.05%. The samples exhibit the three conducti
on mechanisms proposed by Mott and Davis. The activation energy was ca
lculated for each mechanism. The effect of heating rate on the transit
ion temperatures (T-g, T-c, T-m)was studied and the variation of the c
rystallization-peak position was used to calculate the activation ener
gy and the order of the crystallization process.
