The broad-based implementation of thermoelectric materials in converting heat to electricity hinges on the achievement of high conversion efficiency. Here we demonstrate a thermoelectric figure of merit ZT of 2.5 at 923 K by the cumulative integration of several performance-enhancing concepts in a single material system. Using non-equilibrium processing we show...
Thermoelectric materials, which convert heat energy to electrical
energy, may become increasingly important in the world’s energy
situation. Through the inclusion of nanoscale features embedded within
a thermoelectric bulk material, it has been shown that a corresponding
decrease in lattice thermal conductivity results in an enhanced
thermoelectric figure of merit,...
