Ballistic and Diffusive Thermal Conductivity of Graphene

Ballistic to diffusive crossover of heat flow in graphene ribbons.

Heat flow in nanomaterials is an important area of study, with both fundamental and technological implications. However, little is known about heat flow in two-dimensional devices or interconnects with dimensions comparable to the phonon mean free path. Here we find that short, quarter-micron graphene samples reach ~35% of the ballistic thermal conductance limit up to room temperature, enabled ...
