ActiveNanotechnologies—Measurement of the number of layers of graphene-related two-dimensional (2D) materials—Optical contrast method
纳米技术 石墨烯相关二维材料的层数测量 光学对比度法
Application Summary AI generated
This standard specifies the optical contrast method for measuring the number of layers in graphene-related two-dimensional materials, such as few-layer graphene flakes. It is applied in research laboratories and quality control settings within the nanotechnology and advanced materials industries, particularly for characterizing graphene samples produced via mechanical exfoliation or chemical vapor deposition. The method relies on optical microscopy to compare the contrast difference between the material and its substrate, enabling non-destructive layer count verification.
