WebSource: got paid to sit at a microscope with scotch tape and graphite Edit: If you think that's cool, consider that one of the alternative methods to using scotch tape is to literally take a razor blade (like the kind you'd stick into Halloween candy) and VERY carefully shave the graphite. You can get a single atomic layer of graphene doing ... Initial attempts to make atomically thin graphitic films employed exfoliation techniques similar to the drawing method. Multilayer samples down to 10 nm in thickness were obtained. Earlier researchers tried to isolate graphene starting with intercalated compounds, producing very thin graphitic fragments (possibly monolayers). Neither of the earlier observations was sufficient to launch the "graphene gold rush" that awaited macroscopic samples of extracted atomic planes.
WebScotch-tape-like sulfur-assisted exfoliation of graphite is developed to produce the graphene –sulfur composites and freestanding low-defect graphene sheets.
