What it is
A method that grows 30-inch graphene sheets by chemical vapour deposition on copper and transfers them by rollers onto flexible plastic. It showed graphene could be made over large areas as a transparent electrode.
It was published in Nature Nanotechnology in 2010; growth of graphene on copper foil had been shown earlier by Rodney Ruoff's group (Science, 2009).
What it led to
- flexible touchscreens with graphene electrodes
- large-scale production of large-area graphene
- Korean research in flexible electronics
