Abstract :
We discuss the thermoelectric transport coefficients and the figure of merit of realistic quantum well and quantum wire superlattice systems. The electronic contribution to the transport is described in detail by including the effects of the heat current along the barriers, of carrier tunneling through the barriers, of well width dependence of the scattering rates, and of lifting of the valley degeneracy in realistic superlattice systems. The lattice thermal conductivity is described by including the effects of interface scattering
