Comment on "Dirac electrons in a dodecagonal graphene quasicrystal"
arXiv:1808.08730
Abstract
In a recent letter, Ahn and Moon, et al. (2018) studied the quantum states of Dirac electrons in a two-dimensional structure realized by epitaxial growth of twisted bilayer graphene rotated exactly 30 degrees. They claim this structure to be a graphene quasicrystal with dodecagonal quasicrystalline order. However, as we show in this comment, it is not a quasicrystalline structure, but a Moire pattern.
