We have found a calculation mistake for the Grüneisen parameter (γG), which was caused by the mistake in calculating the lattice vibration heat capacity value at 300 K (CV) by the Dulong–Petit law; the number of atoms in a formula unit was missing in the calculation. The γG values [Tables I, II, Fig. 4(b), p. 071002-1 abstract/line 3, and p. 071002-4 left column/line 1 from the bottom] should be replaced with the data in the following text and table. In addition, we have found a display error for the volume thermal expansion coefficient (βV) and bulk modulus (B) in Table II, while the correct values were used for calculating γG in the original article. 1) The βV values [Table II and p. 071002-3 right column/lines 4−3 from the bottom] should be replaced with the data in the following table. The B values [Table II and p. 071002-4 left column/lines 1−2] should be replaced with the data in the following table. Note that, except for the calculation results on γG and CV, Eqs. (1)–(3), the experimental methods, and the data used for calculation were correct. The revised values of γG are 0.13, 0.20, and 0.18 for x= 0, 0.5, and 1.0, respectively. The correct values of CV, γG, βV, and B have been listed in the following Tables I and II. Figure. 4(b) has been revised using corrected γG. Although the absolute values of γG corrected here are smaller than those reported in the original article, 1) the trend that the Se concentration of γG is clearly linked to the Se concentration dependence of Bi-rattling phonon energy is consistent with the main conclusion in the original article. Therefore, the essence and the conclusion of this study are unaffected by the correction of the parameters.
