Graphene, a single layer of carbon

Position 1: Despite these advantages, the challenge of producing defect-free graphene at industrial scale continues to limit its widespread commercial application.

Position 2: Its extraordinary properties arise directly from this two-dimensional structure, which confines electrons to movement along a flat plane.

Position 3: Beyond electronics, its exceptional tensile strength—approximately two hundred times that of steel—makes it a promising reinforcing agent in composite materials.

Position 4: Graphene, a single layer of carbon atoms arranged in a hexagonal lattice, has attracted enormous scientific interest since its isolation in 2004.

Position 5: As a result, charge carriers travel through graphene at remarkably high speeds, giving the material an electrical conductivity that surpasses copper.
