A group led by deHeer observed the fractal nature of resistance vs. magnetic field plots in this material, and a paper by Ostrovsky et al. proposed a model for the anomalous quantum hall effect observed in it based on Anderson localization instead of Landau level structures.

Depositing it epitaxially on substrates such as silicon carbide can induce a band gap which it lacks because its conduction and valence bands meet at vertices of its Brillouin zones. Electrons moving through this material obey the Dirac equation for relativistic fermions, which allows one to test the Klein paradox, and it is also known for its ballistic transport of electrons, which makes it a valuable material for field-effect transistors. First isolated by Andre Geim and Kostya Novoselov in 2004, for twenty points, identify these sheets of sp2 hybridized carbons, which can be stacked to form graphite.
