Since its discovery in 2004, graphene has become a highly prized material in electronics applications owing to its unusual electronic structure. Although graphene is only composed of carbon atoms, what makes graphene’s material properties so different from other carbon allotropes, such as graphite, is the fact that it is a two-dimensional (2D) material. 2D materials are atomically thin in one dimension with a periodically repeating unit cell in the other.
Within a graphene sheet, the carbon atoms are bonded such that each carbon has essentially two free electrons that can be delocalized throughout the sheet-like structure and can act as a conductor. Overall, the thinness of the sheets results in a highly flexible materials, that have both excellent thermal and electrical conductivity, making them an excellent candidate for transistors. Many variants of monolayer graphene exist, with the introduction of dopants into the structure
