Graphene is a two-dimensional material that has been named after the small-like structures that make up its structure. It was discovered in 2004 by three researchers from the University of MIT and the University of California, Berkeley.

The research team, led by Dr. K. David Liu and Dr.Li, used a process called chemical vapor deposition (CVD) to grow graphene on a silicon wafer. The process involves exposing a silicon wafer to a gas containing carbon atoms, which causes the carbon atoms to bond together to form a network-like structure.
When the wafer is cooled, this network-like structure forms into a single layer of graphene. The structure of the graphene sheet is highly unique and is characterized by the presence of a hexagonal lattice of carbon atoms. This means that each atom is connected to every other atom through six bonds, making it an extremely strong and conductive material.
In addition to its exceptional electrical properties, graphene also exhibits excellent thermal stability and mechanical strength. Its high surface area allows for large quantities of electrons to be present on its surface, which enhances its electrical conductivity. Furthermore, graphene can be shaped and strained to form thin films and superthin films, which have a number of applications in electronics, energy storage, and other fields.
While graphene was discovered in the early 21st century, the full potential of the material has only recently been realized. Graphene has shown promise as a replacement for traditional materials such as silicon and aluminum, due to its exceptional electrical and thermal properties. Some scientists believe that graphene could revolutionize the field of electronics and energy storage by replacing traditional materials with more efficient and cost-effective solutions.

Despite its remarkable properties, graphene is still a relatively new and emerging material. Further research is needed to fully understand its behavior and potential uses. However, the discovery of graphene has opened up a new era of innovation and discovery in the field of materials science, and it is likely that we will see many exciting developments in the coming years.
