A recent flood of research scholarship on electronic transport in low-dimensional (2-D or 1D) materials like graphene or carbon nanotubes reflects the tremendous potential of these materials to unveil a deeper understanding of the laws that govern the sometimes surprising emergent behavior of electrons. Scientists have probed novel materials like these to uncover the physics of topological superconductivity and topological insulators. But one of the biggest challenges researchers face in studying real materials is the presence of uncontrolled impurities that influence electronic transport.
