Figure 3

The scattering rates from three-phonon interactions (a) at  K and  K using 300 K IFCs and 700 K IFCs, respectively; (b) at  K using, respectively, 300 K IFCs and 700 K IFCs; and (c) at  K with one set of 3rd-order IFCs substituted by those obtained at  K. The color-coded mode Grüneisen parameters projected onto the phonon dispersions at (d)  K and (e)  K.
