Nanostructuring also affects the electron mean-free paths, so the same bonudary-scattering formalism was applied to investigate the impact on the electrical transport properties. The inclusion of the additional scattering term is expected to decrease the conductivity, power factor and electronic thermal conductivity. On the other hand, the total thermal conductivity, i.e. the sum of lattice and electronic thermal conducitivities, is expected to decrease, which may compensate for the decreased power factor to increase the overall ZT.
