The measurement of dc conductivity as a function of pressure in the range 0 ≤ P < 2.0 GPa for Se 75 In 25— x Pb x ( x = 0, 5, 10, 15) glasses are reported. n‐type Se–In–Pb glasses show a maximum in the resistance versus pressure. Differential Scanning Calorimetric (DSC) studies have also been carried out for the measurement of the glass transition temperature ( T g ). The results have been explained in terms of the presence of fourfold coordinated Pb atoms in the Se–In host matrix.
