Scotch Tape, N2 Pencils and Batteries: Junk Drawer or the Makings of a Superconductor?
Energy levels and their separation are one of the key contributors to electronic properties observed in materials. One such level, the Fermi level, is of particular import and one way to modify its position is by the application of an electric field across one’s sample. It has been predicted that if a certain net charge could be induced in graphene, an atomically thin sheet of graphite, the resultant field would cause the Fermi level to shift to the extent that superconductivity could be observed. Our goal is to use a technique known as electrochemistry to slide cations in between sheets of graphene, with the hope that this theoretical vision can be achieved.
