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

Figure 7

Visualization of the effective phonon energy curves, (see (46); solid curves), for ZnSe and ZnTe. Included are the corresponding discrete points ((); cf. Table 5), for integer and several negative half integer orders. For comparisons with counterparts following from former theoretically calculated PDOS spectra we have shown here also the respective series of discrete values obtained via detailed numerical analyses of the theoretically calculated PDOS spectra presented for ZnSe and/or ZnTe in [32] (×), [36] (), [45] (◊), [46] (△), [66] (+), and [89] (☆). The series of even-order values (for to 10, listed in Table 10), which have been determined in Appendix C via the conventional analyses procedure for Debye temperature values representing the harmonic lattice, (cf. Figure 10), are represented by squares (□).
