The calculated model made it possible to predict the main result of studying graphene on faceted surfaces, which revealed the graphene ability to coat geometrically nonuniform surfaces with a curved continuous film. Stacked van der Waals (vdW) heterostructures where semiconducting two-dimensional (2D) materials are contacted by overlaid graphene electrodes enable atomically thin, flexible electronics. The calculations showed that the strong chemical interaction of carbon with nickel leads to a significant bending of the graphene layer (up to few angstroms). In contrast to graphene on Ni(111), which forms a solid coating with a (1 × 1) structure, graphene on Ni(110) forms a complex crystal structure which is substantially distorted by interaction with the substrate. The calculated model made it possible to predict the main result of studying graphene on faceted surfaces, which revealed the graphene ability to coat geometrically nonuniform surfaces with a curved continuous film.ĪB - Experimental investigation and computer simulation of a graphite monolayer (graphene) on different Ni single-crystal surfaces have been performed.
The name is derived from 'graphite' and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds. N2 - Experimental investigation and computer simulation of a graphite monolayer (graphene) on different Ni single-crystal surfaces have been performed. Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice nanostructure. T2 - Experimental and theoretical investigation TEM, FT-IR and EDX spectroscopy were also performed to confirm the synthesis of graphene nanosheets including the functional group identification and quantitative analysis for elements, respectively.T1 - Graphene morphology on Ni single-crystal surfaces The obtained graphene nanosheets were also confirmed through the computational data by Gaussian09, where the peaks at 1379 cm − cm −1 for D and G band, respectively, make a good agreement with experimental data. In addition, a broad 2D band at 2790 cm −1 confirm the presence of few layer graphene nano sheets. Raman spectroscopy was performed on the obtained residue, where the observed D and G bands at 1342 cm − cm −1, respectively, confirm the synthesis of graphene nano sheets. firstly at 400 ☌ in presence of nanoclay followed by at 750 ☌ under nitrogen atmosphere was performed to obtain a black charged residue.
The present work reports a cost effective, environment friendly and mass production capable method for upcycling of solid plastic waste into value added product (graphene). We confirm that both of these nonequilibrium transport effects hold for different types of bonding of Gr on the Ni(111) surface while maintaining Bernal stacking between individual Gr layers. Graphene is a smart material that responds to any physical change in its surrounding environment. Waste plastic management and converting it into value added products is one of the greatest challenges before the scientific community. During the last few years graphene has emerged as a potential candidate for electronics and optoelectronics applications due to its several salient features.
