Reviewer 2 Report

 

This work introduced a combined Raman spectroscopy and magnetotransport measurements in disordered graphene. This study is not new, but it stills contains some interesting. Therefore, the paper can be accepted after the revision.

 

1- Besides Raman, at least the authors should perform SEM and/or AFM analysis to characterize the surface morphology and the homogeneity in physico-chemical properties of their graphene.

2- The authors should provide the Raman spectra after oxygen plasma exposure as they commented on text.

3- The authors should improve the conclusion of their work by putting a little more details.

Reviewer 3 Report

I have following comments:

1.The problem of electron beam induced contamination, which is almost always present in SEM is not discussed. The hydrocarbons adsorbs may cause buildup of polymeric carbon on the surface. Authors should be aware of this problem.

2. Instead of Fig.1a which shows Raman spectra on selected sites on the surface of the sample I would suggest to present I(D)/I(G) versus electron dose diagram, such as it is in M.M.Lucchese et.al., Carbon 2010, 48, 1592–1597. Information about size of created defects could be obtained.

3. I would suggest to add I(2D) versus I(G) diagram such as it proposed in Lee, J.E. at al., Nat. Commun. 2012, 3, 1024. Such diagram could connect disorder with type of carriers

4. Citation of literature concerning damaged of graphene is not complete: for example influence of damage on electrical and optical properties of graphene should be mentioned [G.Gawlik, et al.  https://doi.org/10.3390/app9030544 ]

5. Literature on weak localization in graphene should be more complete. There is lack of citation of one of the first papers on this problem: https://aip.scitation.org/doi/figure/10.1063/1.4905418
