Surface chemical analysis atomic force microscopy Method for measuring thickness of molybdenum disulfide sheet material1 ScopeThis document specifies a method for measuring the thickness of layered molybdenum disulfide nanosheets using atomic force microscopy. This document is suitable for the measurement of the thickness of layered molybdenum disulfide nanosheets transferred or grown on the surface of a solid substrate. The thickness of molybdenum sulfide nanosheets is no more than 100nm, and the thickness measurement of other similar nanosheet materials can also refer to this method.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text.

Note 1.This size range usually, but not exclusively, exhibits characteristics that cannot be extrapolated from larger sizes. For these characteristics, the upper and lower limits of the scale Is approximate. Note 2.The purpose of introducing a lower limit (about 1nm) in this definition is to avoid considering a single atom or cluster of atoms as a nano-object or a nano-structure unit. [Source. GB/T 32269-2015, 2.1] 3.2 Nanomaterial Any material whose external dimension, internal or surface structure is at the nanometer scale. [Source. GB/T 30544.1-2014, 2.4, with modification] 3.3 Nano-object One-dimensional, two-dimensional, or three-dimensional objects whose outer dimensions are on the nanoscale Note. A general term used for all nano-scale objects that are separated from each other. [Source.
