Heat flows at an atomic level

A single layer of atoms can be used to enhance or restrict heat flow between materials.

The finding comes as researchers try to develope a greater understanding of heat transfer by refining the techniques used to measure heat flow.

Heat-flow control is a central component of integrated circuitry, combustion engines and technologies that harvest energy from waste heat, yet this has been hampered by incomplete knowledge about the specifics of heat transfer.
