Graphene is a two-dimensional material that has fascinated scientists and engineers for decades due to its unique properties. Its discovery was a significant milestone in the field of materials science, as it opened up new possibilities for electronic devices, energy storage, and other applications.
(who discovered graphene)
The first report of the existence of graphene was published in 2004 by scientist Alexei Togusovsky. He conducted experiments on a single layer of graphene using the scanning tunneling microscopy technique and found that it had electrical conductivity four times higher than that of silver and three times higher than that of copper.
Togusovsky’s findings were promptly confirmed by another researcher named Peter Schrödinger, who used high-resolution scanning electron microscopy to demonstrate the presence of a lattice structure composed of hexagonal boron nitride (h-BN) atoms. This structure was called the honeycomb lattice, and it played a crucial role in determining the electronic properties of graphene.
In 2008, physicist J.C. Fick was one of the first researchers to confirm the existence of graphene via transmission electron microscopy. He performed experiments on a graphene film grown on a silicon substrate and found that it had electrical conductivity at room temperature of over 10^9 S/m, which is significantly higher than that of conventional conductors.
Fick’s work was soon followed by several others who confirmed the existence of graphene through various experimental techniques. In 2010, researchers confirmed the presence of graphene by creating a layer of graphene on a surface made of carbon nanotubes. The graphene layer had a chemical composition of graphene oxide, while the carbon nanotube layer acted as an insulating layer between them.
Since then, the discovery of graphene has become a major milestone in the field of materials science, and its potential applications have been widely recognized. Graphene has been used in electronic devices such as solar cells, sensors, and micros due to its high electrical conductivity and excellent mechanical strength. It has also been shown to be promising in energy storage, where it can store electricity in a non-renewable way.
graphene has been applied in a variety of industries, including automotive, aerospace, and construction. For example, graphene has been used to create lightweight and strong composites for aircraft wings and wind turbines. In addition, graphene has been explored for use in electronics and data storage, as well as in medicine and drug delivery.
Despite its many potential applications, graphene remains a relatively new material, and much research is still needed to fully understand its properties and behavior. Researchers are continuing to explore new ways to grow graphene on surfaces and develop new methods for controlling its properties.
