利用扫描隧道显微镜（STM）和基于密度泛函理论（DFT）的从头算方法研究了Ag（110）表面自对准的石墨烯蜂窝状硅纳米带. STM清晰地观察到银衬底上的硅蜂窝结构，而DFT计算证实了Si原子自发地采用这种新的硅结构。(C)2010年美国物理学会。[doi：10.1063/1.3419932]
Scanning tunneling microscopy (STM) and ab initio calculations based on density functional theory (DFT) were used to study the self-aligned silicon nanoribbons on Ag(110) with honeycomb, graphene-like structure. The silicon honeycombs structure on top of the silver substrate is clearly observed by STM, while the DFT calculations confirm that the Si atoms adopt spontaneously this new silicon structure.
