Rp. Webb et al., THE FORMATION OF DIAMOND-LIKE CARBON-FILMS DUE TO MOLECULAR IMPACTS ON GRAPHITE, DIAMOND AND RELATED MATERIALS, 7(8), 1998, pp. 1163-1166
Molecular dynamics simulation is used to investigate the formation of
diamond-like carbon films due to energetic impacts of large molecules
such as fullerene C-60, bucky tubes C-100 and C-200 and polyethylene o
n a graphite surface. The local densification around the impact site a
nd the consequent change in the bonding of both the constituent atoms
of the striking molecule and the struck graphite target surface are an
alysed as a function of the energy per particle of the incoming molecu
le. Simulation data are presented in the relative probability of formi
ng sp(3)- and sp(1)-bonded carbon from the energetic collision of thes
e molecules with the surface. It is found that the ratio of sp(3) and
sp(1) bonds create peaks at around 100 eV per atom. (C) 1998 Elsevier
