a–d hot-pressed-only, and e–h hot-pressed-annealed samples. a, e Electrical conductivity σ. b, f Seebeck coefficient S. c, g Thermal conductivity κ. d, h Figure of merit ZT. The κ and ZT calculated by both the measured-Cp and Dulong-Petit-Cp and those reported15,16,27 are presented. The gray double arrows indicate the significant discrepancy observed on the hot-pressed-only samples. The measured-Cp are provided in Supplementary Information Supplementary Fig. 2.
