Abstract
The lattice thermal conductivity of lead telluride has been investigated theoretically as a function of grain size, level of doping and alloying. Although there is some difficulty in making predictions of the precise dependence of the lattice thermal conductivity on these parameters, it is possible to indicate the range over which the results may vary. It is concluded that for moderately doped material having a grain size of 1 mu m the reduction in lattice thermal conductivity would lie in the range 4-6% for unalloyed lead telluride and 11-13% for highly disordered alloys.Keywords
