Fig. 4

Red and blue lines represent the calculated values using the Boltzmann transport approach in the directions perpendicular and parallel to the trigonal [111] axis, respectively. The purple line represents the average values of the computed lattice thermal conductivity. The grey region represents the experimental results collected from refs. 25–32.
