Paper Abstract

The long-range charge transfer correlated with the existence of fractal nanostructure for thin Fe-containing Langmuir-Blodgett (LB) films of thiophene derivatives has been experimentally observed. Band structure of the film with hexagon crystal structure has been simulated assuming 26 carbon atoms and one(or two) Fe atom in cluster in elementar cell and validity of adiabatic approximation. The simulations display, that the energy of the structure is reduced when taking into account the ferromagnetic ordering. This leads to the stabilization of the structure. Dynamically invertible instability of band structure at changes of spin polarization is considered as appearance of photo-induced quasi-steady states of nanostructured LB-films. Temperature Green function method has been proposed to examine relativistic corrections for Fermi system which are caused by non-sphericity of atom potential in leaky packed solids. The origin of quasi-stationary modes in Dirac problem is considered for an electron in the vicinity of the ionization threshold in a strong oscillating magnetic field.
