Research on influential factors of low-energy C36 cluster deposition on diamond (100)crystal plane
Brenner-LJ Potential is adopted to describe the interactivity between diamond and C36 cluster, and the deposition mechanism of multi-C36 on the diamond surface is researched by molecular dynamics simulation. Through simulative experiments the incident energy, incidence point, incidence posture, incidence angle and other factors are analyzed. Studies discover that the minimal deposition threshold is 20eV and the maximum is 60eV with the different incidence point locations and incidence postures of C36 clusters. When the incidence angle is not over 60°, C36 may roll or slip to the region of smaller bonding energy and then bond. So the bonding probability is raised. Research results show that when incidence angle is between 0° and 20° and incident energy range is from 30eV to 60eV, it is the optimal condition of single C36 cluster deposition on diamond (100) crystal plane.
