are mainly based on resonant surface enhanced. Raman: : The radiation is not absorbed or emitted, but shifted in frequency.

The, raman spectrum of graphene, as shown in figure 2, includes several peaks intro to response essay which are well distinguished and understood. However, in order to gain a better insight into the materials quality characteristics, rapid and reliable techniques that provide the right property measures are required. Owing to its size and optical properties, graphene is not visible on majority of substrates. Conclusion, raman spectroscopy has proven to be an effective technique for analyzing the innovative nanomaterial, graphene. In addition, the G band is sensitive to doping and both the line width and frequency of this peak can be employed to check the doping level. In Raman spectroscopy, UV, Vis or NIR lasers can be used as light t source. Raman scattering (sers) and Raman scattering (RRS). Energy difference -gives information of chemical structures E o -h Laser Combined AFM- Confocal Raman Cantilever AFM -gives information of surface properties Both chemical structural features can be analysed simultaneously 27 Applications 28 Information from Raman Spectroscopy and what can be used for Mapping characteristic.
