Frequency-dependent phonon mean free path in carbon nanotubes from nonequilibrium molecular dynamics
Frequency-dependent phonon mean free path in carbon nanotubes from nonequilibrium molecular dynamics
Owing to their long phonon mean free paths (MFPs) and high thermal conductivity, carbon nanotubes (CNTs) are ideal candidates for, e.g., removing heat from electronic devices. It is unknown, however, how the intrinsic phonon MFPs depend on vibrational frequency in non-equilibrium. We determine the spectrally resolved phonon MFPs in isotopically …
