Figure 5. (A) Thermal conductivity (κ); (B) lattice thermal conductivity (κL) and (E) the figure of merit (zT) as a function of temperature for the 3 GPa, 4 GPa, and 5 GPa samples; (D) Schematic diagram illustrating potential phonon scattering mechanisms for reducing lattice thermal conductivity; The comparison of (C) κL and (F) zT values between this work and literature data.
