Over the last years interest in thermoelectricity for microharvesting or for prospective large-scale conversion of heat into electric power has reignited. This was mostly due to the tremendous impact of nanotechnology onto the conversion rate achievable by thermoelectric generators, which rose by almost a factor of three over the last decade. New classes of thermoelectric materials have appeared - while old materials have come back into focus. Nanowires and nanolayers, along with multilayered structures, have imparted to many well-known materials new improved characteristics. As performance has remarkably enhanced, much attention is now dedicated to selecting materials and technologies that could be scaled up and brought to bulk production. On this avenue, geo-abundance and low material costs are key issues.
This Special Issue will be devoted to the most important advances in Silicon, SiGe alloys, and silicides. It will feature some mini-review papers and selected research contributions, spanning from theoretical and experimental research on nanostructured materials to the technology enabling implementation of silicon and silicon-related materials in actual thermoelectric generators.
