Physics - Shining a Light on Chiral Symmetry Breaking in Graphene
Shining a Light on Chiral Symmetry Breaking in Graphene May 19, 2021• Physics 14, 76 Sensitive photoemission measurements visualize the signatures of a symmetry-broken phase of graphene with carriers of mixed handedness. C. Bao Figure 1: (a) Graphene lattice and unit cell (orange diamond) highlighting the distinct A and B sublattices (inset). (b) Schematic of graphene pseudospin chirality around each Dirac point ( K and Kʹ) in the graphene Brillouin zone (orange hexagon). (c) Graphene with a lattice of lithium atoms creating a new Kekulé-O bond pattern (purple diamond). (d) The K...
