Getting through the Nature of Silicene: An sp<sup>2</sup>–sp<sup>3</sup> Two-Dimensional Silicon Nanosheet
By combining experimental techniques with ab-initio density functional theory calculations, we describe the Si/Ag(111) two-dimensional system in terms of a sp 2 -sp 3 crystalline form of silicon characterized by a vertically distorted honeycomb lattice.We show that 2D sp 2 -sp 3 Si NSs are qualified by a prevailing Raman …
