Fig. 5: Characteristic Raman peaks before, during and after intercalation.
From: In-plane staging in lithium-ion intercalation of bilayer graphene
a Evolution of the G peak position with intercalation. Individual spectra are shifted for clarity. Corresponding values of the gate voltage, \({V}_{{{{\rm{g}}}}}\), are shown as labels. The intercalated state corresponds to \({V}_{{{{\rm{g}}}}}=\) 4.0, 4.5, and 5.0 V. The Black dashed line emphasizes the shift of the G peak in the intercalated state. b Same as in (a) for the 2D peak. Source data are provided as a Source Data file.
