H. Plank et al., DEPOSITION AND HYDROGEN CONTENT OF CARBON-FILMS GROWN BY CH3-BEAM BOMBARDMENT( ION), Journal of applied physics, 78(9), 1995, pp. 5366-5372
Carbon deposition and hydrogen codeposition is investigated as a funct
ion of ion energy, fluence, and target temperature at normal incidence
by bombardment of silicon and pyrolitic graphite substrates with mass
selected CH3+ molecules. An amorphous hydrogenated carbon layer (a-C:
H) is formed in a thickness range of 40-130 nm at a fluence of 3x10(18
)/cm(2). The deposition process, the re-erosion phenomenon, the hydrog
en content, and the WC ratios of the carbon films are studied between
300 and 1000 K in the ion energy range from 150 eV to 3 keV. The exper
imental results are compared with those of TRIDYN computer simulations
and previous experimental results of carbon sputtering by atomic H+ a
nd C+ beams in order to obtain a better understanding of the interacti
on between hydrocarbon ions and the carbon-based wall materials in fus
ion devices. (C) 1995 American Institute of Physics.
