Raman study on defective graphene: Effect of the excitation energy, type, and amount of defects
Open accessAbstract
We present a detailed Raman study of defective graphene samples containing specific types of defects. In particular, we compared ${\mathit{sp}}^{3}$ sites, vacancies, and substitutional Boron atoms. We find that the ratio between the $D$ and $G$ peak intensities, $I$($D$)/$I$($G$), does not depend on the geometry of the defect (within the Raman spectrometer resolution). In contrast, in the limit of low defect concentration, the ratio between the ${D}^{\ensuremath{'}}$ and $G$ peak intensities is higher for vacancies than ${\mathit{sp}}^{3}$ sites. By using the local activation model, we attribute this difference to the term $C$${}_{S,x}$, representing the Raman cross section of $I$($x$)/$I$($G$) associated with the distortion of the crystal lattice after defect introduction per unit of damaged area, where $x$ $=$ $D$ or ${D}^{\ensuremath{'}}$. We observed that ${C}_{S,D}=0$ for all the defects analyzed, while ${C}_{S,{D}^{\ensuremath{'}}}$ of vacancies is 2.5 times larger than ${C}_{S,{D}^{\ensuremath{'}}}$ of ${\mathit{sp}}^{3}$ sites. This makes $I$($D$)/$I$(${D}^{\ensuremath{'}}$) strongly sensitive to the nature of the defect. We also show that the exact dependence of $I$($D$)/$I$(${D}^{\ensuremath{'}}$) on the excitation energy may be affected by the nature of the defect. These results can be used to obtain further insights into the Raman scattering process (in particular for the ${D}^{\ensuremath{'}}$ peak) in order to improve our understanding and modeling of defects in graphene.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
