Abstract
The measurement of dc conductivity as a function of pressure in the ra nge 0 less than or equal to P < 2.0 GPa for Se75In25-xPbx (x = 0, 5, 1 0, 15) glasses are reported. n-type Se-In-Pb glasses show a maximum in the resistance versus pressure. Differential Scanning Calorimetric (D SC)studies have also been carried out for the measurement of the glass transition temperature (T-g). The results have been explained in term s of the presence of fourfold coordinated Pb atoms in the Se-In host m atrix.
