Nanostructured thermoelectrics: the new paradigm?
- Materials Science Division
This review discusses recent developments and current research in bulk thermoelectric materials in which nanostructuring is a key aspect affecting thermoelectric performance. Systems based on PbTe, AgPb{sub m}SbTe{sub 2+m}, NaPb{sub m}SbTe{sub 2+m}, Bi{sub 2}Te{sub 3}, and Si are given particular emphasis. To date the dramatic enhancements in figure of merit in bulk nanostructured materials come from very large reductions in lattice thermal conductivity rather than improvement in power factors. A discussion of future possible strategies is aimed at enhancing the thermoelectric figure of merit of these materials.
