Thermoelectricity is capable of direct energy conversion between heat and electricity, promising low-grade heat harvesting and solid-state cooling for the transition to sustainable electronics. Currently, bulk Bi2Te3 polycrystalline undergoes a composite synthesis process that typically encompasses melting, ball milling, hot pressing, and spark plasma sintering, aiming to introduce a myriad of structural defects for enhanced performance.
