Scale Invariance of the Structure upon Explosive Crystallization of Amorphous Films

In the last few years an interest in field of quantum dots devices creating has been increased. In this work the nanocrystallite with Frank-Kasper structure was examined as the quantum dot in amorphous film. An ability to create all-inorganic Quantum Dots Light Emission Device may be considered for Tb30Fe70, Co80C20 and Co50Pd50 films. The self-organisation of atomic structure in Tb30Fe70, Co80C20 and Co50Pd50 films, which possess large values of perpendicular magnetic anisotropy (PMA) constant (K-perpendicular to similar to 10(6) erg/cm(3)), were investigated by methods of electron diffraction and transmission electron microscopy, including the method of bend contours([1]). The crystallization of the films proceeds in an explosive way forming different dissipative structures from initial nanocrystalline state. In previous works([2,3]) it was shown that after crystallization (T-ann similar to 260-330 degrees C) the atomic structures of Tb30Fe70 Co80C20 and Co50Pd50 films are tetrahedrally close-packed Frank-Kasper structures. In this work the structural model of thin film at mezoscale and its correlation with magnetic and optical properties is proposed.
