Introduction

Because graphene has many excellent properties (such as electrical conductivity and thermal conductivity), it has caused people both academically and commercially in the past decade.

They are of great interest. Recently, other materials with similar graphene structures have also shown good performance, for example, single layer and few layers of hexagonal nitrogen.

Boron (hBN), molybdenum disulfide (MoS2), tungsten diselenide (WSe2), silicene, germanene, and mixtures of these materials

a layered assembly of matter. The thickness of these materials is limited to nanometers or smaller and consists of one layer to several layers. Because these materials have a dimension

Degrees are on the order of nanometers or smaller, while the other two dimensions are usually larger than the nanoscale and are therefore referred to as two-dimensional (2D) materials. Layered material is made up of

A two-dimensional layer in which these two-dimensional layers form a three-dimensional structure by weak stacking or weak bonding. Figure 1 shows two-dimensional materials and graphite

An example of a different stacking structure in aene. It should be noted that the two-dimensional material in reality does not have to have a flat topography, and there may be warped knots.

And can further form aggregates and agglomerates with different morphologies. Two-dimensional materials are an important part of nanomaterials.

a) A variety of two-dimensional materials consisting of different elements and structures (in different colors of the ball, top view, side to try to show)

b) Bernal stacking bilayer graphene (3.1.2.6) c) chaotic layered graphene or twisted bilayer graphene with relative stacking angle (3.1.2.7)

Figure 1 Two-dimensional material and different stacking structures of graphene layers

d) Bernal stack (AB stack) (3.4.1.10) three-layer graphene (3.1.2.9)

And rhombohedral stack (ABC stack) (3.4.1.11) three-layer graphene (3.1.2.9)

Figure 1 (continued)

It is important to standardize graphene, derived from graphene and related two-dimensional materials at the international level, and their related publications,

The number of patents and organizations is rapidly increasing, and they are also being commercialized and sold worldwide, so these two-dimensional materials need one

The terminology.

This section is one of a series of terminology standards for different aspects of nanotechnology. This part is based on GB/T 30544.3,

ISO /T S80004-6 and ISO /T S80004-11 are compiled and used as much as possible.
