Keywords:

Graphite,Phonon,Nanoscale heat transfer

In graphite, momentum-conserving phonon-phonon scattering (normal scattering) is dominant, and the formation of second sound and phonon Poiseuille flow have been reported. The observation of even more pronounced phonon hydrodynamic heat transport phenomena in isotope-purified graphite will be presented.
