文摘

The synthesis of silicene, graphene-like silicon, has generated very strong interest. Here, we reveal the growth of high aspect ratio, perfectly straight, and aligned silicon nanoribbons, exhibiting pyramidal cross section. They are multistacks of silicene and show in angle-resolved photoemission cone-like dispersion of their 蟺 and 蟺* bands, at the X̅ point of their one-dimensional Brillouin zone, with Fermi velocity of 1.3 脳 10⁶ m sec^鈥?, which is very promising for potential applications.
