The present work is devoted to a numerical and experimental investigation of the probe supply of “cold” methane on the growth of diamond structures during gas-jet deposition. The analysis of results of experiments on the diamond gas-jet synthesis from methane and hydrogen mixture flows are presented. The direct simulation Monte Carlo method for numerical analysis of gas-dynamic aspect of these experiments was applied. A one-dimensional approach based on the solution of equilibrium chemical kinetics equations was used to analyze gas-phase methane decomposition. The obtained results can be useful for investigation of gas-jet deposition of diamond structures.
