Content introduction:

Graphene is a real two-dimensional crystal system, and its unique physical properties make it widely used in optics, electricity, optoelectronics and so on. Two single-layer or multilayer graphene can be stacked in different layers and rotating angles to form a multilayer graphene heterojunction. These heterostructures compared with its subsystems (single or multi-layer graphene) physical properties more abundant, provided endless possibilities for the study of graphene, but also had a great influence on the performance of the design and construction materials.This report will introduce some of the results obtained by using micro Raman spectroscopy to study graphene materials. For example, It inclucde the number of characterization of multilayer graphene, the heavy doped graphene Fermi level by multi wavelength laser Raman scattering, experimental study of ultra low energy electron excitation near the multilayer graphene Dirac point, multilayer graphene interlayer coupling angle, multilayer graphene interface interaction and resonance Raman spectroscopy etc..
