Debye temperature in crystals at temperature T = 0 K

Khidirov Irisali 1, Rakhmanov Sayfiddin 1, Fazilov Muslim 2


Based on the analysis of the thermal crystal lattice vibrations Debye theory basic assumptions and experimental data accumulated for recent years, a formula is proposed that relates the Debye temperature at moderate temperatures qD and at absolute zero temperature q0 (T = 0 K). It is shown that the calculated Debye temperature q0 at the absolute zero temperature according to the proposed formula in the range from ~ 2 to ~ 13 % coincides with the experimental data taken from literature for a number of substances of different classes.
