On the thermal physical properties of the bulk solid body layers with a fractal structure

Within the framework of the Debye model the fractal structure of the bulk solid layer is analyzed. Changing the fractal dimension can be associated with structural relaxation and do not always correspond to phase transitions. At high temperatures the fractal dimension is constant, while at low temperatures it may be set depending on the external conditions (at a given temperature and pressure). We derive expressions for the isochoric heat capacity, taking into account the temperature dependence of the fractal dimension and the generalized equation of state.
