Abstract:
A method of constructing a fractal model of noncrystalline solid substance is considered using the example of amorphous silicon. In systems of iteration functions, the physical meaning of dihedral and valence angles of the elementary crystallographic cell is assigned to arguments. The model adequacy is estimated by the radial distribution function, the atomic structure density, the distribution of valence and dihedral angles, and the density of dangling interatomic bonds.
