Outline of Final Research Achievements

High-performance thermoelectric materials and module based on lead chalcogenides (PbX (X：S, Se, Te)) were developed by controlling their structures at all length scales from crystal atomic to nano, micro, and milliscopic. The layered chalcogenides with layers of PbX and bismuth chalcogenide (PbX-Bi2X3) were synthesized from elemental Pb, Bi, and X. In sintered compacts of PbX-Bi2X3, the layered crystal structures and highly oriented microtextures enhance the thermoelectric figure of merit ZT. In milli-scale thermoelectric module, the sintered compacts of PbTe having nanostructure has been used for thermoelectric legs. The power generation of this module has been demonstrated at high temperature.
