| Abstract: | The process of atomic hydrogen emission in EACVD in CH_4/H_2 gas mixture is simulated by Monte Carlo method. The relationship between the number of H,CH_3 and the ratio of atomic hydrogen emission line intensity under different experimental conditions was investigated. A method of gaining the optimum experimental condition for diamond film deposition by the atomic hydrogen emission line is given. The result is of great importance to depositing high quality diamond films by controlling the conditions of technology efficiently. |
