Abstract

Molecular dynamics computer simulations of the growth processes and microstructural properties of amorphous carbon (a:C) and amorphous hydrogenated carbon (a:CH) ultra-thin films have been performed. Films 1 to 10 nm thick were grown on a diamond (100) surface using Brenner’s[1-2] bond-order potential for hydrocarbons. The stoichiometry, radial distribution function, chemical bonding (amount of sp2 and sp3 hybridization) and residual stress are presented.
