The developed multiscale approach describes in detail the formation of individual tracks and inter-track interaction in various amorphizable (Y3Al5O12, Mg2SiO4) and non-amorphizable (Al2O3, MgO) dielectrics. A comparison between the modeling and high-resolution transmission electron microscopy analysis of SHI irradiated samples allows to validate the developed model and to investigate links between the basic properties of the materials and features of the kinetics of structural transformations of the targets. We outline an influence and importance of each successive stage of excitation and relaxation on final observable structure modifications within tracks, starting from the SHI induced electronic excitation, electrons and holes transport, energy exchange with the target lattice, transient excitation and relaxation of the atomic system, and ultimate damage formation.
