WebJan 1, 2024 · The D peak located at around 1350 cm −1 represents the disorder in the graphite layer. The D peak appears when the incident laser focuses on graphene edges. By comparing the D peak of graphene and graphite edges in Fig. 2-17D, two components for the graphite D peak can be found, while the graphene D peak is a single peak. WebJul 1, 2007 · Fig. 5 (b) shows a significant change in the shape and intensity of the 2 D peak of graphene compared to bulk graphite. The 2 D peak in bulk graphite consists of two components 2 D 1 and 2 D 2 [36], [38], roughly 1 / 4 and 1 / 2 the height of the G peak, respectively.
