| Hot filament and microwave plasma CVD micro- nanocrystalline diamond films are analysed by visible and ultra-violet excitation source Raman spectroscopy. The sample grain size varies from 20 nm to 2 μm. The hydrogen concentration in samples is measured by SIMS and compared to the grain size, and to the ratio of sp2 carbon bonds determined by Raman spectroscopy from the 1332 cm−1 diamond peak and the sp2 1550 cm−1 G band. Hydrogen concentration appears to be proportional to the sp2 bonds ratio. The 3000 cm−1 CHx stretching mode band intensity observed on the Raman spectra is decreasing with the G band intensity. Thermal annealing modifies the sp2 phase structure and concentration, as hydrogen outdiffuses. |

Hot filament and microwave plasma CVD micro- nanocrystalline diamond films are analysed by visible and ultra-violet excitation source Raman spectroscopy. Hot filament and microwave plasma CVD 微納米晶體金剛石膜以可見和紫外激發(fā)光源拉曼廣譜法加以分析。The sample grain size varies from 20 nm to 2 μm.樣品晶粒大小為20nm到2μm不等。 The hydrogen concentration in samples is measured by SIMS and compared to the grain size, and to the ratio of sp2 carbon bonds determined by Raman spectroscopy from the 1332 cm−1 diamond peak and the sp2 1550 cm−1 G band. 樣品中氫的濃度以SIMS測量并和晶粒尺寸以及由拉曼光譜測得的1332 cm−1金剛石峰的sp2碳帶和1550cm-1的G帶sp2之比相比較。Hydrogen concentration appears to be proportional to the sp2 bonds ratio. 氫濃度好像是與sp2譜帶比成比例。The 3000 cm−1 CHx stretching mode band intensity observed on the Raman spectra is decreasing with the G band intensity. 在拉曼光譜上觀測到，3000cm-1的CHx伸展模式譜帶的強度隨G帶強度增加而減小。Thermal annealing modifies the sp2 phase structure and concentration, as hydrogen outdiffuses.熱處理時，氫向外擴散，sp2相的結(jié)構(gòu)和濃度被修改。 不懂你的專業(yè)，但結(jié)構(gòu)沒問題吧，請結(jié)合專業(yè)理解 |
