Abstract
In this paper, Cu doped PbSe is successfully synthesized by solid state reaction. Theinfluence of porosity on thermal and electrical transport in Cu doped PbSe is investigated in this study. Low densified material significantly scatters the electrons as well as phonons through the high number of scattering sites (like pores, cracks, disorder, etc). As a result, the drastic reduction in thermal conductivity and electrical conductivity isnoticed. Additionally, Seebeck coefficient enhances in a low densified materials. Furthermore, Pb1-xCuxSe (x ∼ 0 to 0.06) has high Seebeck coefficient due to the energy filtering effect and lower charge carrier concentration.
