Graphene is a two-dimensional material that has attracted significant attention in recent years due to its unique electronic properties. One of the most promising applications of graphene is as an electrical conductor, which allows it to conduct electricity without getting hot or losing its ability to store energy.

In a standard graphene sheet, there are thousands of carbon atoms arranged in a hexagonal lattice structure. Each carbon atom can exist either in aσ- or Ï€-characterized state, and this configuration determines the number of charge carriers present on the sheet. Graphene’s electronic properties arise from the intermolecular interactions between the atoms, which can be described by the London dispersion forces.
When graphene is exposed to an electric field, the charge carriers behave like electrons, moving in opposite directions and carrying positive and negative charges. The conducting property of graphene arises from the formation of Cooper pairs, which are pairs of charge carriers that can move through the material without resistance. When an electron and a hole cross each other at a specific point on the surface of the sheet, they can form a Cooper pair, allowing them to move together as a single entity.
One of the key challenges in realizing practical applications of graphene for electrical conductivity is understanding the mechanisms underlying the formation and behavior of Cooper pairs. There are several theoretical models that have been proposed to describe the electronic properties of graphene, but they remain difficult to apply in practice due to the complexity of the materials involved.
Another important factor in determining the potential of graphene for electrical conductivity is the temperature at which the material becomes thermoelectric. At low temperatures, the thermoelectric effect of graphene is relatively weak, but as the temperature increases, the material’s efficiency as an electrical conductor improves. This is because the increase in temperature leads to the development of more coherent motion patterns within the carbon atoms, which enhances the formation of Cooper pairs.
Despite these advances in our understanding of the electronic properties of graphene, there are still many questions to be answered about how the material stores electricity. For example, what happens when graphene is exposed to a strong magnetic field, and how does this affect its ability to store electricity? Additionally, what are the limits of graphene’s electrical conductivity under different conditions, such as in the presence of impurities or defects?

In conclusion, graphene offers a promising avenue for developing new technologies based on its unique electrical properties. However, further research is needed to fully understand the mechanisms underlying the formation and behavior of Cooper pairs, as well as the limitations of graphene’s electrical conductivity under different conditions. By addressing these questions, we may be able to develop graphene-based technologies that could have significant impacts on a wide range of fields, including electronics, medicine, and energy storage.
