Researchers from Texas State University developed a new method for creating single-crystal arrays of graphene. This is seen as an advance towards manufacturing large quantities of single crystals of Graphene - similar to Silicon wafer production.
The idea is to initiate graphite 'seeds' - hexagonal single crystals, and then grow them on top of a copper foil inside a chamber containing methane gas using a process called chemical vapor deposition. This method can be used to grow an ordered array of thousands or millions of single crystals of graphene.
