Power generation and thermoelectric cooling enabled by momentum and energy multiband alignments

TLDR

Tin selenide thermoelectric materials can convert heat into electricity or serve as the basis for cooling devices. The study aims to identify optimal contact materials to make this approach attractive for future applications. Doping tin selenide with lead and sodium improves room‑temperature thermoelectric properties by manipulating electronic bands, enabling the material to be used for both power generation and cooling. Qin et al.

Abstract

A cooler tin selenide Thermoelectric materials can convert heat into electricity or be used as the basis of cooling devices. Qin et al . found that doping a tin selenide thermoelectric material with lead and sodium improved the room temperature thermoelectric properties, an effect created by manipulation of the electronic bands. The authors showed that the material could be used not only for power generation but also cooling. If optimal contact materials are identified, then this approach may be attractive for future applications. —BG
