| Abstract: | The samples of
selenium rich Se85Cd15-xZnx (x= 0, 3, 7, 11 and 15) have been prepared by slow cooling of melt
technique. The pellets of the samples have been prepared at constant load of 10
ton (pressure of 866 Mpa). Measurements of effective thermal conductivity (λe)
and effective thermal diffusivity ( e) of selenium rich Se85Cd15-xZnx pellets, have been
carried out at room temperature using transient plane
source (TPS) technique. From the measured values of λe and e,
specific heat per unit volume (Cp,
derived quantity) of these samples in the composition range of investigation,
have been determined. The variations of effective thermal conductivity and effective thermal diffusivity of Se85Cd15-XZnx with composition have
been explained on the basis of binding energy of the alloys formed and mean
free path of the phonons. |
