对“十二角形石墨烯准晶中的狄拉克电子”一文的评论

Comment on "Dirac electrons in a dodecagonal graphene quasicrystal"

Tongxu Yu, Longguang Liao

摘要:

在最近的一封信中,Ahn和Moon等人(2018)研究了二维结构中狄拉克电子的量子态,该二维结构是通过精确旋转30度的扭曲双层石墨烯的外延生长实现的。他们声称这种结构是具有十二方准晶顺序的石墨烯准晶。然而,正如我们在这篇评论中所展示的,它不是准晶结构,而是莫尔图案。

英文摘要:

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.
