Graphene Sheets Get Easier To Manufacture

grunaura writes "South Korean researchers have devised a way to create graphene sheets one centimeter square using a hydrocarbon vapor on heated nickel. It's touted as being more efficient than the current process where graphene sheets are pressed, and there is evidence that 'the quality of graphene grown by chemical vapour deposition is as high as mechanically cleaved graphene.' Graphene is relatively new, but not to Slashdot. This round of news highlighting the technology focuses on the bendable nature of graphene sheets, as opposed to the memory applications or capacitive properties discussed here previously. These films are the closest we have come to superconductors at room temperature."

Isn't it likely that further refinements will only marginally improve the effectiveness? Unless it is really close to being a room-temperature superconductor already, I don't see them achieving their goal with graphene.

It hasn't been shown to be superconducting but its conductivity is orders of magnitude better than silicon (which comprises most of a computer chip -- even the interconnects). I don't think anyone is thinking superconductor applications but rather a silicon successor kind of thing that is evolutionary rather than revolutionary.
