Graphene – Disordered Superconducting Bilayers

We aim to push frontiers of knowledge in the area of condensed matter physics with the focus on novel quantum phases in 2D systems. Combining state-of-the-art nanotechnology sample preparation, electronic transport, magneto-transport and spectroscopy measurements at low temperatures we hybridize two systems that exhibit unique quantum phases: monolayer Graphene and disordered superconducting films. The former is a single atomic layer of carbon that exhibits a number of quantum phenomena such as quantum hall effect and quantum hall ferromagnetism. The latter is a system that undergoes a superconductor to insulator quantum phase transition and has been claimed to exhibit exotic quantum phases such as a “Bose metal” and a “Bose insulator”. Our preliminary results presented below show promising signs for novel phases due to the combination of the two systems.
