Frictional Characteristics of Atomically Thin Sheets

Using friction force microscopy, we compared the nanoscale frictional characteristics of atomically thin sheets of graphene, molybdenum disulfide (MoSSUB2/SUB), niobium diselenide, and hexagonal boron nitride exfoliated onto a weakly adherent substrate (silicon oxide) to those of their bulk counterparts. Measurements down to single atomic sheets revealed that friction monotonically

[11, 12] Although, NWs are commonly fabricated on Silicon and conventional III‐V substrate for several years, the recent discovery of graphene sheets in 2004 [] has stimulated extensive research interest as an alternative platform for NWs growth.

Growth from Below: Graphene Bilayers on Ir(111)

We elucidate how graphene bilayers form on Ir(111). Low-energy electron diffraction (LEED) reveals that the two graphene layers are not always rotationally aligned. Monitoring this misalignment during growth shows that second-layer islands nucleate between the existing layer and the substrate. This mechanism occurs both when C segregates from the Ir and when elemental C is deposited from above

2016/10/7In contrast to the common trend whereby only non-polar faces of hexagonal 4H and 6H polytypes were used for graphene growth, Hens et al [] developed a new approach for graphene growth using thermal decomposition of (001)-oriented cubic silicon carbide.

Realization of free

The available synthesized silicene-like structures have been only realized on metallic substrates which are very different from the standalone buckled silicene, e.g., the Dirac cone of silicene is destroyed due to lattice distortion and the interaction with the substrate. Using graphene bilayer as a scaffold, a route is proposed to synthesize silicene with electronic properties decoupled from

We report on the development of a new technique for the growth of graphene and graphite nanocrystals from a metal–carbon melt. The process involves dissolving carbon inside molten nickel or copper at a specified temperature and then allowing the dissolved carbon to nucleate and grow on top of the melt at a lower temperature. The morphology of graphite forming inside nickel is shown to depend

Silicene

Silicene is a two-dimensional allotrope of silicon, with a hexagonal honeycomb structure similar to that of graphene. Contrary to graphene, silicene is not flat, but has a periodically buckled topology; the coupling between layers in silicene is much stronger than in multilayered graphene; and the oxidized form of silicene, 2D silica, has a
