Introduction
Graphene is composed of a single layer of carbon atoms arranged in a hexagonal honeycomb lattice: Due to its excellent electrical, optical, mechanical and thermal properties, such as
Such as high mobility, high transmittance, good flexibility and high thermal conductivity, it has broad application prospects in many fields: Defect concentration as an evaluation
It is an important parameter for estimating the quality of graphene and has an important impact on its mobility, thermal conductivity, mechanical properties, etc: Therefore, the defect concentration of graphene is
The measurement can not only reveal its intrinsic properties from a scientific perspective, but also provide technical guidance for the production and application of graphene:
Raman spectroscopy technology has the advantages of high efficiency, accuracy, non-destructiveness, simple sample preparation, and the ability to measure large areas, and has been widely used:
In quality testing of graphene: Raman spectroscopy technology can measure various properties of graphene, such as the number of layers, doping levels, stress levels and
Defect concentration, etc: Under a specific excitation light energy, the defect concentration of graphene is directly related to the peak area ratio of the D mode and G mode of its Raman spectrum:
Therefore, the defect concentration of graphene can be measured through Raman spectroscopy:
