Key Points

  • The aim is to achieve high thermoelectric efficiency in Mg3Sb2-based materials across a wide temperature range, especially near room temperature.
  • Investigated the effects of strain on grain-boundary reconstruction in Mg3Sb2-based alloys.
  • Analyzed the relationship between microstructure and charge transport properties.
  • Evaluated thermoelectric performance at near-room temperatures.
  • Achieved high thermoelectric performance in Mg3Sb2-based alloys at near-room temperatures.
  • Demonstrated that optimized microstructures enhance low-temperature charge transport.
  • Revealed a successful strategy for overcoming challenges in material efficiency.

Abstract

Achieving high thermoelectric efficiency across wide temperature range, including near room temperature, within a single Mg3Sb2-based material remains challenging, because the microstructures that favor low-temperature charge transport often conflict with...
