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

Figure 5

Effective Debye temperature values, , as resulting for ZnTe from measured (isobaric) heat capacities, ([46] (), [38] (□), [31] (+), [10] (◊), [80] (), and [81] ()). The continuous curve for the true Debye temperature, (– – – – –), is due to (28) in combination with (9) for the isochoric (harmonic) heat capacity shape function, (according to the parameters listed in Table 1). The continuous curve for effective Debye temperature, (solid curve), is due to (27) and (28) in combination with (5) and (9) for the associated isobaric (anharmonic) heat capacity shape function, . The dotted curve (in the inset) shows the low-temperature dependence of the true Debye temperature, , according to (30).
