Orbital magnetic states in moiré graphene systems - Nature
Graphene is a semimetal whose conduction and valence bands meet at the Dirac points, which are six locations in momentum space, the vertices of its hexagonal 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 separate it from other condensed … WebApr 7, 2024 · Graphene nanoribbons (GNRs), which are quasi-one-dimensional polyacene sheets with a width of less than 100 nm and a bandgap between 1–1.6 eV, offer a better solution to the shortcomings of ...
