Heat guiding and focusing using ballistic phonon transport in phononic nanostructures
Heat conduction at the nanoscale is unlike macroscopic diffusion and phonons can travel in straight lines without dissipation. Here Anufrievet al. show that heat conduction can be spatially directed in nanostructured silicon and exploit this effect to concentrate heat into a focal point.
