Kurzbeschreibung (Abstract)
Raman spectroscopy is able to probe disorder in graphene through defect-activated peaks. It is of great interest to link these features to the nature of disorder. Here we present a detailed analysis of the Raman spectra of graphene containing different type of defects. We found that the intensity ratio of the D and D′ peak is maximum (13) for sp3-defects, it decreases for vacancy-like defects (7), and it reaches a minimum for boundaries in graphite (3.5). This makes Raman Spectroscopy a powerful tool to fully characterize graphene.
