To better understand how thermoelectric devices convert thermal energy into electricity at the atomic scale, researchers used neutrons to study single crystals of tin sulfide and tin selenide. The results revealed a strong correlation between changes in the structure at certain temperatures and the frequency of atomic vibrations (phonons). This allowed the researchers to identify temperatures ideal for energy conversion and provided basic scientific knowledge for designing new thermoelectric materials.

A new ‘gold standard’ compound for generating electricity from heat
Researchers show in a new study that a single material, a layered crystal consisting of the elements rhenium and silicon, turns out to be the gold standard of transverse thermoelectric devices.
