ABSTRACT

The specific heat capacity of half-Heusler ScNiSb and TmNiSb compounds have been calculated using a simple approximation in the temperature range 0–298 K. The results obtained for the specific heat capacities are in good agreement with the experimental data in the literature. The Debye temperatures were derived by fitting the analytical expression obtained in this study to experimental data. The Debye temperatures and the Sommerfeld coefficients resulting from the fitting are 355.95 K and 7.19 mJ/mol.K for ScNiSb, and 234.5 K and 14.92 mJ/mol.K for TmNiSb.

热电半霍斯勒XNiSb（X = Sc，Tm）化合物的比热容的理论研究

抽象的

半霍斯勒ScNiSb和TmNiSb化合物的比热容是使用0-298 K温度范围内的简单近似值计算得出的。比热容的结果与文献中的实验数据非常吻合。通过将本研究中获得的分析表达式与实验数据进行拟合，得出德拜温度。由拟合得出的德拜温度和Sommerfeld系数对于ScNiSb是355.95 K和7.19 mJ / mol.K，对于TmNiSb是234.5 K和14.92 mJ / mol.K。
