Controlling the Properties of Graphene using CVD Method: Pristine and N-doped Graphene

Electrochemical properties of CVD grown pristine graphene: monolayer- vs. quasi-graphene.

We report the electrochemical properties of pristine monolayer, double layer and few-layer (termed quasi-) graphene grown via CVD and transferred using PMMA onto an insulating substrate (silicon dioxide wafers). Characterisation has been performed by Raman spectroscopy, optical spectroscopy, Atomic Force Microscopy and X-ray Photoelectron Spectroscopy, revealing 'true' pristine single-layer gra...

Synthesis and structural properties of Mn-doped ZnO/Graphene nanocomposite

Zinc oxide (ZnO) is a promising metal oxide semiconductor with various applications, especially in the photocatalytic destruction of environmental pollutants. However, this nanoparticle has some limitations, such as poor dispersion, aggregation, and a wide energy gap. As such, the doping of metal oxide semiconductor has been strongly recommended. Addition of manganese (Mn) has proven effective ...

Characterization of FeCl3 Intercalation Doped CVD Few-Layer Graphene

Intercalation doping has been theoretically and experimentally studied on chemical vapor deposition synthesized few-layer graphene. Density functional theory calculations identified FeCl3 as a good dopant to reduce the sheet resistance of few-layer graphene. A simple vapor transfer method is employed to dope graphene. The successful doping is confirmed by the Raman spectra as well as the electr...

Superconducting Properties of Graphene Doped Magnesium Diboride

The CVD graphene transfer procedure introduces metallic impurities which alter the graphene electrochemical properties.

High quality graphene films can be fabricated by chemical vapor deposition (CVD) using Ni and Cu as catalytic substrates. Such a synthesis procedure always requires a subsequent transfer process to be performed in order to eliminate the metallic substrate and transfer the graphene onto the desired surface. We show here that such a transfer process causes significant contamination of the graphen...
