Graphene chemical makeup

Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K'. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero.

Aerographene or graphene aerogel is, as of April 2024 , the least dense solid known to exist, at 160 g/m (0.0100 lb/cu ft; 0.16 mg/cm ; 4.3 oz/cu yd), less than helium. It is approximately 7.5 times less dense than air. Note that the cited density does not include the weight of the air incorporated in the structure: it does not float in air.
