Graphene is a two-dimensional material that has attracted significant attention due to its exceptional electrical conductivity, which is four times greater than that of copper. This property makes it an ideal material for various applications such as electronics, energy storage, and aerospace.
(what makes graphene so conductive)
One of the key factors that contribute to graphene’s high electrical conductivity is its unique structure. Graphene is composed of layers of carbon atoms arranged in a hexagonal lattice. Each layer has six carbon atoms and forms a strong bond between adjacent layers. The absence of direct contacts between the layers allows for free flow of charge, which results in high electrical conductivity.
Another important factor that affects graphene’s electrical conductivity is its chemical composition. Graphene contains functional groups such as carbons, nitrogen, oxygen, and hydrogen, which allow it to absorb and release electrons efficiently. This explains why graphene can be used as a conductor without forming delamination or recombination bands.
The electrical conductivity of graphene also depends on the temperature at which it is synthesized. At low temperatures, the formation of defects in the graphene lattice leads to reduced electrical conductivity. However, when graphene is heated above its critical temperature (around 300°C), the lattice defects begin to form new bands, resulting in improved electrical conductivity.
Graphene’s exceptional electrical conductivity also stems from its high surface area. Since each carbon atom in a graphene layer has six neighbors, there are many available sites for electrons to attach and move through. This increases the number of free carriers in the material, leading to higher electrical conductivity.
