Thermal Stress Analysis of Large Area Diamond Films

摘要: 建立了直流電弧等離子體噴射CVD大面積金剛石沉積數學模型.對襯底上方等離子體中的化學環境進行了模擬計算,并與在相同條件下對等離子體的光譜結果進行對比,發現計算結果與實驗結果基本上吻合.在模擬條件下CH基團可能是促使金剛石生長的主要活化基因.模擬結果顯示CH基因沿徑向的均勻分布對大面積金剛石膜生長有較大的意義.

Abstract: Numerical model for large area diamond film deposition by DC Arc Plasma Jet CVD method is proposed. Chemical environment over the substrate surface during diamond growth were calculated, and was compared with experiment data from optical emission spectrum obtained at similar conditions. It was found that the CH radical may be main active precursor responsible for diamond growth. The overall uniform distribution of CH radical is important for large area deposition of diamond films.-
