One way to think of graphene is as a single layer of graphite, where all the carbons exist in a regular hexagonal array. Being composed of carbon makes graphene a non-metal, but it possesses semiconducting properties that means it often characterized as a quasi-metal.
Graphene是什么意思
Did you know?
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.
