Correction to: J Mater Sci: Mater Electron (2022) 33:17842–17854 https://doi.org/10.1007/s10854-022-08648-1

An article of this title was published in the Journal of Material Science: Material in Electronics (2022) 33: 17842–17854. Unfortunately, an error occurred in the calculation of % change in the relevant parameter mentioned in Table 4 and the related explanation in the text. The corrections are incorporated in Table 4 and should be read as presented below:

Table 4 Experimental values and percentage changes are tabulated from the experimental data of Mg_2-δSi_0.35-xSn_0.65Ge_x (δ = 0, 0.02, 0.04) and (x = 0, 0.05) at 523 K

The followings are the instances influenced due to correction in Table 4 and must be read as follows:

Page 17842 (abstract), line (14–17): Should be read as “The synergetic confluence of improved power factor and low thermal conductivity in Mg_1.98Si_0.3Sn_0.65Ge_0.05 resulted in the highest $ZT$ value of 0.08 at ~ 523 K, which is ~ 300% higher than the $ZT$ value (~ 0.02) of the parent Mg₂Si_0.35Sn_0.65 alloy”.

Page 17851, line (14–18): Should be read as “At room temperature, ${k}_{L}$ of Ge doped alloys are nearly ~ 61% lower than that of the parent alloy, suggesting that Ge substitution increases phonon scattering due to the complexity of band structure”.

Page 17851, line (36–41): Should be read as “Overall, we observe that $ZT$ increases by ~ 300% and ~ 290% in Mg_1.98Si_0.30Sn_0.65Ge_0.05 and Mg_1.96Si_0.30Sn_0.65Ge_0.05, respectively, compared to Mg₂Si_0.35Sn_0.65 at 523 K; this further suggests that Ge substitution reduces the bipolar effect, significantly improving the thermoelectric figure-of-merit”.

Page 17851, line (58–62): Should be read as “Furthermore, the increase of $ZT$ by ~ 167% Mg_1.96Si_0.30Sn_0.65Ge_0.05 (this study) than Mg₂Si [61] may be attributed to the reduction of bipolar effect by Ge substitution, which facilitates reduction in thermal conductivity, as discussed earlier”.
