Managing heat transfer at material interfaces is a major challenge for engineers who work on devices ranging from jet engines to personal electronics to nanoscale transistors. The physical and chemical properties that control thermal transport at interfaces between dissimilar materials are poorly understood.

Researchers at the Aalto University School of Chemical Technology have applied atomic layer deposition (ALD) technique to the synthesis of thermoelectric materials. Converting waste energy into electricity, these materials are a promising means of producing energy cost-effectively and without carbon dioxide emissions in the future.
