Using molecular dynamics (MD) techniques and a hydrocarbon potential of Brenner with an increased C–C interaction range, we investigate kinetics of relaxation processes in tetrahedral amorphous carbon films (ta-C) with high sp3 fractions. The struc

A comparative study of clustering of sp 2 -bonded atoms in the as-deposited and annealed tetrahedral amorphous carbon (ta-C) films is presented. The as-deposited ta-C with a grown-in compressive stress of ∼10 GPa is modelled using amorphous network

The processes of deposition and structural relaxation of tetrahedral amorphous carbon (ta-C) films are investigated using atomistic computer simulations. Applying classical molecular dynamics with a modified hydrocarbon potential of Brenner, ion-beam

We present a method to calculate macroscopic bulk stresses in tetrahedral amorphous carbon (ta-C) films grown by a realistic atomic scale simulation of ion-beam deposition. Similar to real as-deposited films, the simulated films have a high content o

Atomic calculations, based on empirical potentials and the method of homogeneous deformation, are presented for the elastic properties of as-deposited amorphous carbon at 0 K. Several structural models of amorphous carbon generated by a realistic mol

Classical molecular dynamics calculations were performed to study the deposition of thin hydrogenated carbon films. Hydrogen-covered diamond {111} and {001}(2 × 1) surfaces were bombarded with energetic acetylene (C2H2) molecules at impact energies

The formation of buried silicon dioxide or nitride layers by high-dose implantation (typically 10 18 ions cm 2 ) of energetic ions at elevated target temperatures is being extensively studied to produce silicon-on-insulator structures for device appl

The roughness evolution of carbon films deposited from hyperthermal species was investigated by AFM. 10 eV C deposition at normal incidence angle starts with formation of 10 nm high islands followed by continuous, sp2 rich films at larger doses with

The evolution of $s{p}^{2}$ hybrids in amorphous carbon (a-C) films deposited at different substrate temperatures was studied experimentally and theoretically. The bonding structure of a-C films prepared by filtered cathodic vacuum arc was assessed b

Ion beam deposition of carbon films was studied by molecular-dynamics simulations. Using an analytic hydrocarbon potential of Brenner with an increased C-C interaction cutoff value, deposition of films with a thickness of up to 10 nm was simulated fo
