The standard "GB/T 40128-2021 Surface chemical analysis, atomic force microscopy, film thickness measurement method of molybdenum disulfide sheet materials" specifies the method of measuring the film thickness of layered molybdenum disulfide nanosheets by atomic force microscopy (AFM). The standard applies to layered molybdenum disulfide nanosheets transferred or grown on a solid substrate, and the measurement range is from single layer to film thickness of molybdenum disulfide nanosheets not exceeding 100 nm. The standard provides detailed measurement methods and operation guidelines, and can be used for Film thickness measurement of similar nanosheet materials, providing important technical support for related research and applications.
