ised in terms of porosity, coordination number and radial distribution function, and the particle–particle or pore–pore connectivity is analysed with the Voronoi or Delaunay tessellation. The force structures and their link with jamming states are also discussed. Structural properties are shown to be correlated with porosity which links directly to the cohesive force acting on a particle.

摘要

We simulate the {100}-oriented diamond f/lm growth of chemical vapour deposition (CVD) under different models in C-H and C-H-Cl systems in an atomic scale by using the revised kinetic Monte Carlo method. The simulation results show that: (1) the CVD diamond film growth in the C-H system is suitable for high substrate temperature, and the film surface roughness is very coarse; (2) the CVD diamond film can grow in the C-H-Cl system either at high temperature or at low temperature, and the film quality is outstanding; (3) atomic Cl takes an active role for the growth of diamond film, especially at low temperatures. The concentration of atomic Cl should be controlled in a proper range.
