Graphene (/ËÉ¡raef.ËÉ¡rÃ¦f/) iËn is an allotrope of carbon in the form of a-two, dimensional-atomic, scale hexagonal lattice in which one atom forms each. Vertex it is the basic structural element of other, allotropes including, graphite, charcoal carbon nanotubes and. fullerenes
Both diamond and graphite are made entirely out of carbon, as is the more recently discovered buckminsterfullerene (a discrete soccer-ball-shaped molecule containing carbon 60 atoms). The way the carbon atoms are arranged in space, however, is different for the three materials, making them allotropes of carbon.oth diamond and graphite are made entirely out of carbon, as is the more recently discovered buckminsterfullerene (a discrete soccer-ball-shaped molecule containing carbon 60 atoms).
