Formation and coalescence of linear chains in growth of nanostructured sp-sp2 amorphous carbon films

摘要：

Formation and coalescence of linear chains are studied in low-energy atom-by-atom deposition of nano structured sp-sp2 amorphous carbon films. At the energy of 1 eV, the adsorption of incident atoms on the top of the surface atoms and on the top of existing chain-tips prevails, which explains the initial nucle ation and the elongation of sp linear chain structures. During the whole growth process, the film expe riences a transition from a sp-dominated linear chain structure to a sp2-dominated network structure. This transition happens when linear chains get instable beyond the critical length limit, and coalesce into the three-dimensional network structure.
