CVD法制備的石墨烯G峰高于2D
|
||
| 如題,請教大俠,做了幾次都是這樣的,2D峰很尖銳,結(jié)構(gòu)還可以,沒有D峰,但是G峰高于2D峰,我查了相關(guān)的文獻,基本上都是G/2D小于1的是單層,我這樣的是石墨烯只能說明不是單層? |

we set a range of the G to 2D peak ratio from 0.7 to 1.3 and the fwhm of the 2D peak from45 to 60 cm-1 to estimate the bilayer coverage.Those that have a G to 2D peak ratio lower than 0.7 and fwhm of 2D peak lower than 45 cm-1 are considered to bemonolayer graphene, and the samples that have a G to 2D peak ratio higher than 1.3 and fwhm of the 2D peak higher than 60 cm-1 are considered few-layer graphene. 出自“Direct Growth of Bilayer Graphene on SiO2 Substrates by Carbon Diffusion through Nickel” |
