Electrochemical delamination of CVD-grown …

The separation of chemical vapor deposited (CVD) graphene from the metallic catalyst it is grown on, followed by a subsequent transfer to a dielectric substrate, is currently the adopted method for device fabrication. Most transfer techniques use a chemical etching method to dissolve the metal catalysts, thus imposing high material cost in large-scale fabrication.

CVD Growth of Large Area Smooth-edged Graphene …

Defects in a GNM can include point defects and line defects (viz. grain boundaries). The as-grown GNM and the as-produced graphene used as the source for the post-growth etched GNM, were grown under the exactly same CVD conditions, and thus point-defect differences between them can be ignored.

Direct transfer of CVD-grown graphene onto eco …

In this study, cellulose flexible film was used as a supporting substrate for the development of an eco-friendly graphene gas sensor. The flexible cellulose substrate was fabricated by the method reported in the previous study. Graphene was grown on Cu foil using a conventional CVD method and directly transferred onto the cellulose substrate via a wet-transfer method.

Edge-controlled growth and kinetics of single-crystal ...

Controlled synthesis of wafer-sized single crystalline high-quality graphene is a great challenge of graphene growth by chemical vapor deposition because of the complicated kinetics at edges that govern the growth process. Here we report the synthesis of single-crystal graphene domains with tunable edges from zigzag to armchair via a growth–etching–regrowth process. Both growth and etching ...

Hot Carriers in CVD-Grown Graphene Device with a …

Abstract. We investigate the energy relaxation of hot carriers in a CVD-grown graphene device with a top h-BN layer by driving the devices into the nonequilibrium regime.By using the magnetic field dependent conductance fluctuations of our graphene device as a self-thermometer, we can determine the effective carrier temperature at various driving currents while keeping the lattice temperature ...
