Researchers have attempted to use graphene as a replacement for silicon in semiconductor devices. The problem with graphene in its unaltered form is that it does not have a band gap. The basic idea is to chemically modify the graphene so that it retains its unusually high mobility, but introduces a band gap to make it behave like a semiconductor.
