“…Such a phenomenon is also observed in fluoride intercalated graphite. 20 However, the case of fluoride GIC's is similar to the case of fluorine GIC's, since, in the fluorides MF n , where M is a metal, fluorine is the active chemical species that bonds covalently to carbon. In this connection, the other possible candidate of the periodic table for exhibiting a behavior similar to fluorine is oxygen.…”

The structural and electronic properties of fluorine-and bromine-intercalated graphite fibers and HOPG are summarized. In contrast to the bromine intercalate, which is purely ionic for any experimentally attainable intercalate concentration, fluorine has a dual ionic and covalent behavior in graphite. Furthermore, whereas bromine-intercalated graphite is ordered, fluorine-intercalated graphite is disordered. The stiff graphene planes are buckled and islands of various fluorine concentrations are formed. A thermodynamic model is proposed that accounts for the differences between fluorine-and bromine-intercalated graphite materials. The model describes the competition between ionically bonded and covalently bonded intercalate phases of fluorine in graphite. Covalent bonding is more favorable energetically, but an important nucleation barrier exists due to strain and to the destruction of the conjugation of the double bonds.

“…In first, this is electron-electron scattering, which leads to the quadratic temperature dependence of electrical resistivity [15]. However, according to estimates, resulted in a number of works for the second stage GICs with SbF 5 [16], the mean free path of carriers scattering each other is 7⋅10 -5 m at 100 K. This value is significantly greater than the mean free paths at scattering of charge carriers on phonons and boundaries of crystallites. In secondly, this is carrier scattering on phonons, which includes scattering on different modes of graphite and intercalate.…”

The presented work is devoted to investigations of manifestation of quantum effects of weak localization and interaction of charge carriers in electrical conductivity of acceptor graphite intercalation compounds (CICs). As shown by studies intercalation leads to a decrease in the resistivity and to change the resistivity temperature coefficient from negative sign in the source graphite on a positive sign in intercalated graphite. At the low temperature for all GICs specimens the minimum in the temperature dependence of resistivity is observed. In terms of the model of charge carrier's weak localization and interaction for two-dimensional systems temperature dependence of phase relaxation time, localization radius and charge carriers screening constant for all GICs are estimated.
