WebApr 5, 2024 · In the experiments, roughness of graphene decrease versus etching process, implying an un-expanded defect region. These results suggest that the removal of graphene by oxygen plasma is most likely anisotropically vertical etching, i.e., layer by layer etching mechanism is preferred. So it is WebSep 27, 2024 · The graphene etching can be achieved by turning off the CH 4 gas and retaining only the Ar/H 2 flow, where the graphene pattern relied on the Ar/H 2 flow rate ratios. When a relative low Ar/H 2 flow rate ratio of 800/100 sccm was applied, periodical hexagonal holes were engraved into the as-grown graphene sheet.
