WebOct 30, 2024 · Graphene is an atom-thin sheet of carbon atoms arranged in a hexagonal pattern. Stacking two sheets and twisting one by the “magic angle” of 1.1 degrees yields a superconductive material with ... 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.
