New materials could boost energy harvesting from waste heat

AI Insight

This computational study uses first-principles density functional theory calculations to investigate LiHfIrSi and LiHfIrGe quaternary Heusler alloys for thermoelectric energy harvesting applications. The researchers examined the structural, electronic, and thermoelectric properties of these materials, finding they exhibit semiconducting behavior with band gaps suitable for thermoelectric conversion. Both compounds demonstrated promising Seebeck coefficients and figures of merit that suggest potential utility in converting waste heat to electrical energy.


Thermoelectric materials that can efficiently convert waste heat into electricity are critical for improving energy efficiency in industrial processes and electronic devices. Identifying new Heusler alloy compositions through computational screening accelerates the discovery of practical materials for sustainable energy technologies.
