FRACTAL MODEL OF HEAT-CAPACITY FOR SUBSTANCES WITH DIAMOND-LIKE STRUCTURES

Low temperature heat capacity models for substances with diamond-like structures have been considered on the basis of the Debye model and fr actal states filling at fixed characteristic temperature. It was shown that low temperature calorimetry is an efficient tool for scanning th e distribution of the atomic vibrational states in real substances. Fr actal dimension and Poisson's ratio in the elastic-isotropic multifrac tal model are related by a simple interdependence, which enables estim ation of the fractal dimension from elastic properties of solids.
