Can You Buy Graphene Sheets? [Comprehensive Answer]

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. Four electronic properties sep… WebGraphene-based nanoporous materials have been extensively explored as high-capacity ion electrosorption electrodes for supercapacitors.
