A Review on Common Approaches Used for Graphene Characterization

Graphene particularly one layer of carbon atoms in 2D crystal lattice of honeycomb has gain much attention because of its distinctive electronic and optoelectronic properties. The stated characteristics of this material with a unique structure of carbon that in turn opened-up new aspects for the future systems and devices. Despite the graphene is a unique electronic material, synthesizing graphene with a single layer was less investigated. Thus, it is important to cover the main methods used for characterizing the graphene such as Raman, TEM, SEM AFM, XRD and UV-Vis with a view to the fundamental principles of each method.
