Typical Raman spectrum of a Multilayer film Transferred on Glass

Explanation of Raman spectrum

1.    Raman spectroscopy is used to check the presence of a D peak in graphene samples. If a D peak is present, then this can indicate defects in the sample, such as cracks or flaking.

2.    The ratio of the heights of the 2D peak and the G peak indicate the number of graphene layers.
2D>G : Single-layer
2D=G : Double layer
2D<G : more than triple layer

3.    3 measurements for every sample are taken and presented on the same graph.
