Title:
SHOCKWAVE FABRICATION OF THERMOELECTRIC MATERIALS
Document Type and Number:
WIPO Patent Application WO/2010/011709
Kind Code:
A3
Abstract:
The explosive consolidation of semiconductor powders results in thermoelectric materials having reduced thermal conductivity without a concurrent reduction in electrical conductivity and thereby allows the construction of thermoelectric generators having improved conversion efficiencies of heat energy to electrical energy.
