carbon material
without long-range crystalline order. Short-range order exists, but with deviations of the interatomic distances and/or interbonding angles with respect to the graphite
lattice as well as to the diamond
lattice.Note:
The term amorphous carbon is restricted to the description of carbon materials with localized π-electrons as described by P. W. Anderson (Phys. Rev., 1958, 109, 1492). Deviations in the C–C distances greater than 5% (i.e. , where is the inter-atomic distance in the crystal lattice for the as well as for the configuration) occur in such materials, as well as deviations in the bond angles because of the presence of 'dangling bonds'. The above description of amorphous carbon is not applicable to carbon materials with two-dimensional structural elements present in all and an extension greater than .
