Abstract

We uncover a new regime of nanoscale thermal transport that dominates when the separation between heat sources is small compared with the substrate’s dominant phonon mean free paths. Surprisingly, the interplay between neighboring heat sources can facilitate efficient, diffusive-like heat dissipation.
