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

Figure 3

Fitting of the set of data () provided for ZnTe by Kremer et al. [46] in combination with the upper section (102 K < < 327 K) of the data set given by Gavrichev et al. [38] (□), a set of approximate data points due to Gadzhiev et al. [80] () (which we have redigitalized from their Figure ), and a series of equidistant (smoothed) data points () available from the SGTE data review [81]. For comparisons with other data available for ZnTe we have also visualized the low-temperature data points given by Demidenko and Maltsev [31] (+) and Irwin and Lacombe [33] (◊), including the smoothed high-temperature data points quoted by Gavrichev et al. [82] (□) [ curve (— ; see (5)) and curve (– – – – –; see (4), in combination with (9) and (14) to (17)].
