The dynamic mechanism of the velocity splitting during the nucleation and growth of silicon nanoparticles produced by pulsed laser deposition is investigated using the Monte Carlo simulation method. Compared with the previous works, the earlier onset and end of the splitting phenomenon are found due to the nucleation and growth of Si nanoparticles in this paper. More importantly, our simulated results are more precisely consistent with the previous experimental data. The extrusion pressure and velocity elasticity of the particle cluster are proposed, it is the imbalance between them that induces the velocity splitting.
