The aim is to explore how pressure influences the structural phase transitions and thermoelectric properties of bulk Mg₃Bi₂.
Characterization of thermoelectric properties under varying pressure conditions
Assessment of structural changes via X-ray diffraction
Evaluation of figure of merit (zT) measurements
An increase in pressure leads to observable structural phase transitions
Enhanced thermoelectric figure of merit (zT) was noted under specific pressure conditions

Resumen

The thermoelectric materials Mg₃Bi₂ and related compounds exhibit a high figure of merit (zT) combined with attractive properties for commercialization, such as low cost, elemental abundance, non-toxicity, and good processability....
