WebHoley graphene sheet is a promising nano-scaled material with a number of applications for electrochemical energy storage and gas sensors. Further, the joining of a carbon nanotube on a holey flat graphene creates new 3D material combining remarkable mechanical properties from both materials. In order to join a carbon nanotube with defect atoms ... 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…
