Unit cells of graphene, the world’s most conducting material, are considered to be both conventional and primitive.
(is unit cell of graphene conventional or primitive)
On one hand, the definition of a unit cell refers to the arrangement of atoms or molecules within a solid or liquid. In the case of graphene, the structure of each atom is a single electron per unit cell, which results in a unique electronic behavior that sets it apart from other materials. The periodicity of the atomic structure means that the arrangement of atoms is repeatable in different directions, which leads to the formation of repeating patterns that make up the graphene structure.
However, on the other hand, the concept of a unit cell also encompasses more than just the atomic arrangement. It includes the number of atoms that make up the structure and their arrangement within the cell. In the case of graphene, each atom has six valence electrons, which is sufficient to form strong interactions with other atoms. However, this does not mean that the overall structure of the graphene sheet can be thought of as being simple. Instead, the unit cell can be viewed as a complex network of interconnected structures that are arranged in such a way that they create an energy landscape that allows for the transfer of electrical charge through the material.

In conclusion, while the definition of a unit cell involves the atomic arrangement of atoms within a solid or liquid, the concept of a unit cell also encompasses the number of atoms and their arrangement within the cell. In the case of graphene, the unit cell is a complex network of interconnected structures that are arranged in such a way that they create an energy landscape that allows for the transfer of electrical charge through the material. This combination of properties makes graphene an intriguing material with many potential applications in fields such as electronics, energy storage, and even medicine.
