In the present paper, the energy band gaps with temperature have been studied in lead sulfide (PbS). The energy band gap is alinear function of temperature. The values of the energy band gap in different temperature are calculated. The calculated val

In the present paper, we have been studied the elastic constants of lead chalcogenides [(PbX, X= Se and Te)] with help of lattice constants. The elastic constant such as Young’s modulus, bulk modulus, shear modulus and Poisson ratio in lead chalcog
