Layered atoms

WebIn materials science, the term single-layer materials or 2D materials refers to crystalline solids consisting of a single layer of atoms. These materials are promising for some applications but remain the focus of research. Single-layer materials derived from single elements generally carry the -ene suffix in their names, e.g. graphene. WebEach graphene layer is connected by Van der Waals forces which are significantly weaker than the carbon to carbon covalent bonds. Graphite’s chemical structure can be seen in Figure 2. ... During graphitization, carbon atoms are rearranged to fill atom vacancies and improve atom layout.
