ABSTRACT: In the
present paper, we have studied the
effect of Ge addition on the physical properties of Se-Sn-Pb chalcogenide ma- terial. The
necessary physical parameters which have important role in determining the
structure and strength of the material viz. constraints, coordination number
etc. have been calculated. The increasing trend has been
found in cohesive energy, heat of atomization and mean bond energy. The glass
transition has been studied using the Tichy-Ticha and Lankhorst approaches,
which also increases with the increasing Ge contents. The increase in these
physical parameters is due to the increasing covalent character in the
material.
