The results demonstrate that this octagonal-hexagonal-square composite structure exhibits low thermal conductivity with the values of 69.3 W/(m·K) and 66.9 W/(m·K) at room temperature along the a- and b-axes, respectively. Detailed analysis reveals that the acoustic modes, especially the out-of-plane acoustic (ZA) mode dominate heat transport due to their long relaxation times, while the optical modes contribute much less despite the high group velocity. The Grüneisen parameter and phase space of scattering processes are also studied, and we find the absorption processes dominate the scattering processes.
