DETERMINATION OF HEAT CAPACITY OF SOME SEMICONDUCTOR COMPOUNDS USING A DELAUNAY'S INTEGRAL

Abstract

Using a numerical Delaunay's method, theoretical values of molar heat capacity C_p were calculated for some semiconductors (GeS, GeSe, GeTe). The obtained results have been compared with the n-dimensional Debye functions and with the corresponding experimental results in the 220-250 K temperature range. The estimated results are in good agreement with both the n-dimensional Debye functions and the experimental results over the entire temperature range. This confirms that the numerical Delaunay's method is able to represent the molar heat capacity C_p of semiconductor compounds.
