Abstract

The expression of the lattice heat capacity of solids as a function of temperature has been obtained in a new theoretical approach, without using the phonons-conception – by the direct analysis of the thermal excitation of atomic vibrations. It allows a quite good qualitatively description of both low and high temperature behaviors of this characteristic. The possibility of the theoretically obtained expression to describe quantitatively experimental temperature-dependence for the specific heat of solids has been demonstrated by fitting the theoretical curve to the experimental points available for β-rhombohedral boron crystal.
