Graphene is a two-dimensional material with unique properties that make it an exciting material for various applications. One of the most intriguing aspects of graphene is its unusual electronic structure, which makes it both a topological insulator and a Dirac fermion.

A Dirac fermion is a quantum-mechanical particle that behaves like a quark (a subatomic particle) in a field. In the case of graphene, electrons move along quantized lines, known as Dirac modes, which are located at specific points on the surface of the material. This property makes graphene an ideal candidate for high-speed electronics, where small transistors can be used to perform complex calculations.
However, despite its extraordinary properties, graphene has not yet been fully understood. One of the main challenges in studying graphene is understanding how it behaves under intense pressure or electric fields, which can cause changes in its electronic structure.
Graphene’s unusual electronic structure is also related to its mechanical stability. Due to its unique crystal structure, graphene can resist deformation at room temperature and maintain its shape even after subjected to intense stress. This structural feature makes graphene a promising material for use in structures such as flexible electronic devices and energy storage systems.

Despite these remarkable properties, there are still many questions about graphene that need to be answered. For example, why does graphene behave so differently under different conditions? How does its electronic structure change under extreme pressures or temperatures? These are some of the questions that scientists continue to explore in order to fully understand graphene’s behavior and potential applications.
