Pressure-induced Structural Phase Transition and Thermoelectric Properties of Bulk Mg₃Bi₂

Key Points

• 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
