Some researchers are investigating other promising ways to make
graphene an effective semiconductor, like using two - layer

graphene could in theory be both faster and experience far less noise from electron jostling than existing silicon
chips.
One advantage
graphene holds over carbon nanotubes is the possibility that it can be manufactured directly as a step in the wafer processing that goes on in
chip factories, instead of being fabricated separately and added later.
