Description
Yu Pei and co-authors show heat flowing in an unusual wave mode along thin ribbons in a 2023 paper. Heat in solids usually spreads by diffusion, carried by short-lived vibrations. At the surface of some materials, light and vibration couple into waves that travel much farther, which could carry heat past the usual limit.
The team shaped ribbons of silica glass only tens of nanometers thick and measured heat flow along them. The wave mode clearly carried heat across distances of many tens of micrometers, at room temperature and above, in a way that breaks the diffusion pattern. Careful design of the ribbon size let the waves couple well to heat sources at each end. The work opens a route to steer heat in tiny devices.
