Abstract

$As_xTe_{l00-x}$ glasses have been found to exhibit interesting thermal crystallization behaviour. Glasses with x < 40 show a single stage crystallization and those with $x \geq 40$ exhibit a double stage crystal- lization. The change in the crystallization behaviour occur at x = 40 in the $As_xTe_{l00-x}$ lasses can be associated with two structural effects namely "rigidity percolation" and "chemical stoichiometric ordering", which coincide at this composition. In the present study, the effect of selenium on the thermal crystallization of $As_xTe_{l00-x}$ glasses has been investigated by differential scanning calorimetry. These studies indicate that the cross over in the crystallization behaviour may primarily be due to rigidity percolation.
