A moiré pattern results from the projection of one periodic pattern to another with relative lattice constant or misalignment and provides great periodic potential to modify the electronic properties of pristine materials. In this Review, recent research on the effect of the moiré superlattice on the electronic structures of graphene and silicene, both of which possess a honeycomb lattice, is focused...
Silicene, a single‐layer‐thick silicon nanosheet with a honeycomb structure, is successfully fabricated by the molecular‐beam‐epitaxy (MBE) deposition method on metallic substrates and by the solid‐state reaction method. Here, recent progress on the features of silicene that make it a prospective anode for lithium‐ion batteries (LIBs) are discussed, including its charge‐carrier mobility, chemical...
Silicene, a new allotrope of silicon in a two-dimensional honeycomb structure, has attracted intensive research interest due to its novel physical and chemical properties. Unlike carbon atoms in graphene, silicon atoms prefer to adopt sp2/sp3-hybridized state in silicene, enhancing chemical activity on the surface and allowing tunable electronic states by chemical functionalization. The silicene monolayers...
We report on the epitaxial growth mechanism of silicene layers fabricated on a Ag(111) surface by molecular beam epitaxial deposition. The coverage effect and the structural defects have been characterized using scanning tunneling microscopy (STM). It is found that substrate temperature plays an important role in the formation of silicene in different structures. Several kinds of defects are observed...
