Graphene and copper are two of the most promising materials in modern science, with significant potential for applications ranging from electronics to energy storage. However, when it comes to conductivity, there is some debate about how much more conductive graphene is compared to copper.
(how much more conductive is graphene than copper)
One of the main reasons for this difference is that graphene has a different electronic structure than copper. Graphene is an atomically thin layer of carbon that forms a single, flat sheet, while copper is a metal that consists of a lattice of electrons that are arranged in a repeating pattern.
In terms of conductivity, the electronic band structure of graphene determines its electrical properties. When graphene is exposed to an electric field, it acts as a conductor, allowing electrons to flow easily between its surface. On the other hand, copper has a higher electron density in its lattice, which makes it less conductive.
However, the amount by which graphene is more conductive than copper can vary depending on the specific application. For example, in the case of graphene-based electronic devices such as solar cells, the increase in conductivity can make them more efficient at converting sunlight into electricity. In contrast, in the case of copper-based electrical components, the increase in conductivity may not be necessary due to the high resistance of copper.
Another factor that affects the conductivity of graphene is its temperature. At lower temperatures, copper has a higher thermal conductivity than graphene, which means that it will heat up faster and lose energy more quickly. This can lead to reduced efficiency in devices such as or refrigerators.

Overall, while there is some debate about the relative conductivity of graphene and copper, both materials have significant potential for use in various fields. As researchers continue to develop new materials with improved properties, we can expect to see even greater advancements in the conductivity of these materials in the future.
