WebNov 9, 2024 · The ability to create graphene from household waste negates one of the highest costs within the production process—the cost of the raw graphite products used in the exfoliation processes (which can be $1000-3500 per ton, compared to coal, which is $25 a ton). Compared to CVD processes, it is also a much cheaper and less-complex method. 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.
