Nr. Gall et al., 2-DIMENSIONAL GRAPHITE FILMS ON METALS AND THEIR INTERCALATION, International journal of modern physics b, 11(16), 1997, pp. 1865-1911
Two-dimensional graphite films (2DGF) on solids are wonderful objects,
real nature-made two-dimensional crystals. Formation on active metal
surface of a 2DGF with extremely high adsorption, chemical and catalyt
ic passivity leads to a number of staggering effects. The review is de
voted to 2DGF on metals and their nature, structure, modes of formatio
n and physico chemical properties. A nature of absorption bond between
PDGF and metal substrate is discussed in details. A special attention
is paid to intercalation of 2DGF - a process when foreign atoms and e
ven molecules (fullerenes C-60 molecules) spontaneously penetrate betw
een graphite film and metal substrate. Modes of intercalation are disc
ussed and a mechanism of it, based on thermal movements of carbon atom
s of a graphite layer, proposed earlier, is used for explanation of ex
perimental data. A new, practically important effect-superefficient di
ffusion of alkaline atoms into transition metal bulk, covered by 2DGF,
is reported.
