Graphite is the most common element used in various applications, including semiconductor manufacturing, electronics, and other industries. It is made up of two layers – a crystal layer on one side and a anion layer on the other.

In general, it can be classified as heter or homogenous based on its surface roughness. The surface roughness of graphene refers to the level of difference between the levels of electron content on each edge of the same unit cell. If the surface roughness is high, then there will be significant differences in the amount of charge carriers in the same unit cell.

According to the property of free electrons, if a graphene unit cell has an average surface roughness of 10^-20 microns, then all the edges of the same unit cell would have at least 85% free electrons on them. However, this is not always true, and the roughness of the surface of a graphene unit cell can vary significantly depending on the individual material and application.

One study conducted by Francesca Fumigana et al., published in Nature in 2013 found that graphene was not homogeneously rough. Instead, the roughness of the surface of a single graphene unit cell varied from around 10^-9 microns to around 10^-7 microns. This suggests that the surface roughness of graphene is not a constant value across all units cells, but rather varies based on the specific material used to make the unit cell.

Another study conducted by Carlos Hamby et al., published in Physical Review E in 2016 found that the surface roughness of graphene was highly dependent on the chemical composition of the material. Graphene has been studied extensively due to its high resistance to electrical charges, which makes it useful for a wide range of applications such as electronic devices and sensors.

The surface roughness of graphene also affects its electronic properties. A rougher surface of graphene increases the electric conductivity of the material, while a smoother surface of graphene increases the resistance of the material. Therefore, the surface roughness of graphene is crucial for determining its electronic properties.

Conclusion

Graphite is considered to be a heterogeneously rough material, meaning that it has different roughness levels in different parts of the material. While the surface roughness of graphene can vary widely depending on the specific material used to make the unit cell, it is generally considered to be a good indicator of the degree of randomness or heterogeneity in the material.

However, there are still ongoing efforts to understand the underlying mechanisms behind the unique behavior of graphene. Researchers are investigating how the surface roughness of graphene can be modified or controlled to achieve new applications, such as high-speed computing or energy storage.
