Preparation and structure of carbon film deposited by a mass‐separated C+ ion beam
TLDR
In this article, it was shown that the carbon film is amorphous and does not contain graphitically bonded carbon atoms, and the atomic density of the film calculated from the energy loss due to the plasma oscillation of valence electrons is 1.7×1023 atoms/cm3, which is in good agreement with that of diamond.Abstract:
Carbon films were deposited using mass‐separated C+ ions of 300 and 600 eV. The films have diamond‐like characteristics such as transparency in the visible spectral region with wavelengths longer than about 650 nm and in the infrared, and high electrical resistivity. Transmission electron diffraction analysis shows that the film is amorphous and does not contain graphitically bonded carbon atoms. Kα x‐ray emission spectrum of the carbon in the film agrees well with that of diamond. In the x‐ray photoemission spectrum of the film, no characteristic energy loss due to π plasmon was observed. The atomic density of the film calculated from the energy loss due to the plasma oscillation of valence electrons is 1.7×1023 atoms/cm3, which is in good agreement with that of diamond. These results indicate that the film deposited using C+ ion beam consists of tetrahedraly bonded carbon atoms.read more

Hard amorphous (diamond-like) carbons
TL;DR: In this paper, a chemical bonding model is developed which describes the arrangement of these sites and which accounts for many of the electronic and mechanical properties of amorphous carbon, including elastic modulus, hardness, wear rate, friction and film adhesion.

Deposition mechanisms for promoting sp3 bonding in diamond-like carbon
TL;DR: In this paper, it is proposed that the sp3 bonding arises from an increased density, owing to carbon ions entering subsurface atomic sites, and an optimum ion energy arises from a balance between the incident carbon ions having sufficient energy to penetrate the surface atomic layer, while minimizing any excess energy dissipated in a thermal spike.
