WebIn this appendix we give the point symmetries of graphene along the high-symmetry lines. Figure A. 1 shows the graphene hexagonal unit cell in real space. At the r point the six-fold rotation axis is normal to the paper (z-axis). At other points in the Brillouin zone the symmetry is reduced, because of the finite k vector. WebJul 29, 2024 · High-symmetry criteria Stationary points or cusps in a band structure can often be found at and along high-symmetry points and line segments in the Brillouin zone due to avoided crossings in...
WebIf there is only one band maximum in the BZ, this point is one of the high-symmetry points of the BZ. However, there can be cases where there are many points which are a band maximum and they are not at one of the high-symmetry points of the BZ. These points however are all connected by a symmetry operation.
