Summary, etc. The effective thermal conductivity (λ<sub>e</sub>), effective thermal diffusivity (χ<sub>e</sub>) and specific heat per unit volume (ρ<em>C</em><sub>p</sub>) of twin pellets of Se<sub>80</sub>In<sub>20-x</sub>Pb<sub>x</sub> (<em>x</em> = 0, 5, 10 and 15) glasses have been measured at room temperature by using transient plane source (TPS) technique. All three parameters have been varied with Pb content and show reversal trend for 5 at. wt.% of Pb. This reversal trend can be explained on the basis of carrier type reversal as a consequence of unpinning of the Fermi level due to incorporation of Pb in Se-In glassy system.
