Analysis of diamond film creation by pulsed optical lattices

摘要

The ability of a chirped pulsed optical lattice to create diamond films using a molecular beam of fullerene molecules is numerically investigated. Two cases, high and low density, are considered. In both cases, the molecular beam was found to impact the substrate at velocities between 10 and 14km/s. The proposed scenario for the diamond coating stems from the generation of high velocity beams of fullerene particles, bombardment of the substrate surface by these beams, successive dissipation of kinetic energy at the surface and drastic increase of pressure and temperature in the interaction region and finally, formation of diamond crystal structure from deposited fullerenes. A possible setup for the film deposition is proposed. It is shown that that such a system could possibly achieve diamond film growth rates in excess of 1.4 mm/s.
