a Phonon intrinsic mean free path lph–ph and intrinsic TC κ∞. The error bars represent standard errors from linearly fitting the 1/κ(L) vs. 1/lph–b curve (see Supplementary Fig. 11). b Phonon VDOS (top) and the corresponding spectral specific heat (bottom). c Longitudinal (vL) and transverse (vT) group velocities.
