Abstract
The anisotropic thermal-conductivity tensor of bulk black phosphorus (BP) for 80 ≤T ≤ 300 K is reported. Despite the anisotropy, phonons are predominantly scattered by Umklapp processes in all the crystallographic orientations. It is also found that the phonon mean-free-paths of BP are rather long (up to 1 µm) in the through-plane direction.
