Unprecedented Integral-Free Debye Temperature Formulas: Sample Applications to Heat Capacities of ZnSe and ZnTe

Figure 10

Fitting by means of (C.1) of the temperature dependencies of the harmonic sections (solid curves) of Debye temperature data, , that were directly resulting from the high-accuracy transformations (via (27) or (28)) of the experimental data points provided by Kremer et al. ( [46]), for natural ZnSe and ZnTe. The extrapolations of the harmonic (concave) versus curve sections to the limit are represented by dashed curve sections. For comparison we have also shown the more or less deviating data points due to data that have been available from earlier studies for ZnSe by Birch (+ [34]) and Sirota et al. (△ [60]) and for ZnTe by Gavrichev et al. (□  ).
