حساب السعة الحرارية Cp لمادة سيلينيد القصدير (SnSe) باستخدام قانون دي لوني

Abstract

Delaunay's law, which is the numerical solution for Debye, was used to determine the theoretical values of heat capacity Cp of tin selenide (SnSe). Temperature range was between 20 K and 500 K, and the Debye temperature used was θD = 220 K.

The results showed that the theoretical values of heat capacity Cp obtained by Delaunay's law were to a large extent compatible with the experimental data, with Lambert Boltzmann distribution, and with n-dimensional Debye functions. This confirms that Delaunay's law derived from Debye's integral law can represent heat capacity Cp with high accuracy.
