A THEORETICAL MODEL FOR CALCULATING THE DEBYE TEMPERATURE OF SOLIDS.

Abstract

The temperature dependence of the Debye parameter of tungsten has been calculated with two modifications incorporated into the original Debye theory of solids. These modifications are: (1) the assumption of a common cutoff wavelength for the elastic waves, and (2) a sinusoidal dispersion relation between the wavelength and the frequency which leads to a frequency dependence of the wave velocities. This model yields results for the Debye parameter which are in accord with experimental measurements. (Author)
