Graphene
Allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometers, graphene is a single layer (monolayer) of carbon atoms tightly bound in a hexagonal honeycomb lattice.
- Layers of graphene stacked on top of one another form graphite, with an interplanar spacing of 0.335 nanometers.
- Van der Waals forces, which can be overcome during exfoliation of graphene from graphite, hold the various layers of graphene in graphite ....
