Heat does not always flow as rapidly near nanostructures as it typically does in solids. Instead, it can go ballistic! Ballistic heat transfer occurs near a tiny device if its size is smaller than the distance a phonon, or lattice vibration, travels before colliding with another phonon. When this happens, heat flow is reduced, and a nanoscale hot spot is created. Ballistic heat transfer away...
