Overview

Randomized trial demonstrates improved thermoelectric performance in GeTe, suggesting greater potential in power generation.

Key Points

  • To enhance the thermoelectric properties of GeTe by introducing In and optimizing its band structure through nanoscale precipitates.
  • Elemental In introduced into Ge0.94Sb0.06Te matrix
  • Nanoscale Sb2Te3 precipitates identified in GeTe matrix
  • Assessment of thermal conductivity reduction and ZT value upgrades
  • Lattice thermal conductivity decreased by 60% at low temperatures
  • Peak ZT value achieved was 2.2 at 773 K
  • Conversion efficiency of the single leg module reached approximately 11.0%
