The character of propagation in graphene nanostructures of quasi-flexural phonons, whose dispersion law differs from that of sound, is analyzed. Based on the calculation of the frequency dependences of the group velocities and the values of the path

We consider the adsorbed benzene monolayer on graphene and show that the monolayer’s structure can be very complicated even for benzene, the simplest representative of the cyclic hydrocarbons. We base this on previous the first principal investigat

The nature of flexural rigidity of graphene monolayers and the formation of the quasi-flexural modes in graphite and graphene nanofilms is explained. It is shown, that in the major part of the band of quasi-continuous spectrum, quasi-flexural modes d

Structural phases in crystal BEDT-TTF under the influence of doping molecules were studied. The system demonstrates the transition from a parallel aligned molecular phase (β-phase) to a new equilibrium state, where the molecules are rotated at a cer

The simple model that can describe structure and charge ordering in complex doped organic crystals is proposed. We consider the quasione-dimensional model of a crystal with chains (stacks) of flat BEDT-TTF molecules. In a chain of large molecules, sm

Among the large number of both fundamental and ordinary studies of various physical parts of nanomaterials, the study of graphene structures, such as nanofilms (bigraphene, trigraphene) and nanotubes is undoubtedly a priority. At first sight, from a
