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
graphÂ·ite. A naturally occurring, steel-gray to black, crystalline form of carbon. The carbon atoms in graphite are strongly bonded together in sheets. Because the bonds between the sheets are weak, other atoms can easily fit between them, causing the graphite to be soft and slippery to the touch.raphÂ·ite.
