Electrostatic Repulsion of graphene layer on metal surface

In summary, To quantify the electrostatic repulsion between H atoms and graphene at the Cu/Ni (111)-graphene interface, you could use Density Functional Theory (DFT) or other theoretical methods such as molecular mechanics or the classical Coulombic method. These methods can calculate the forces and energies within the system and provide an approximate estimate of the electrostatic repulsion.

Dear Member,
Respected Members,

I am working on the behaviour of hydrogen at the Cu/Ni (111)-graphene interface. In case of Ni (111), the atomic H on the interface diffuse inside the the surface. While in case of Cu (111), the H atom stays at the Cu(111)-graphene interface. It seems that H atom experiences more electrostatic repulsion from the graphene in case of Ni (111). Kindly suggest how can I quantify electrostatic repulsion in both cases ? Best wishes

,You could use Density Functional Theory (DFT) to quantify the electrostatic repulsion between H atoms and graphene on both Cu (111) and Ni (111). DFT can be used to calculate the forces and energies between the atoms within a system. By comparing the energies of the systems with and without interactions, you can calculate the magnitude of the electrostatic repulsion. Additionally, you could use other theoretical methods such as the molecular mechanics method or the classical Coulombic method, which provides an approximate estimate of the electrostatic repulsion between two charged particles.
 

1. What is electrostatic repulsion?

Electrostatic repulsion is a phenomenon in which two objects with opposite electrical charges repel each other. This is due to the electric force between the two objects.

2. How does graphene layer affect electrostatic repulsion on a metal surface?

Graphene is a highly conductive material that can carry electric charges. When a graphene layer is placed on a metal surface, it can alter the distribution of electric charges on the surface, leading to a change in the electrostatic repulsion between the graphene layer and the metal surface.

3. What factors can influence the electrostatic repulsion between a graphene layer and a metal surface?

The electrostatic repulsion between a graphene layer and a metal surface can be influenced by the distance between the two objects, the electrical properties of the materials, and the presence of any other external electric fields.

4. Can electrostatic repulsion be used in practical applications involving graphene and metal surfaces?

Yes, electrostatic repulsion can be utilized in various applications involving graphene and metal surfaces, such as in creating electronic devices with improved conductivity and in developing sensors for detecting small changes in electric fields.

5. Are there any potential challenges or limitations to consider when studying electrostatic repulsion of graphene layers on metal surfaces?

One potential challenge in studying electrostatic repulsion of graphene layers on metal surfaces is accurately measuring and controlling the distance between the two objects. Additionally, the presence of impurities or defects on the surface of the materials can affect the electrostatic repulsion behavior.
