Graphene: Quantum Transport in a 2D Membrane


Graphene, a two - dimensional single atomic layer of carbon, has recently emerged as a promising candidate for electronic materials, as well as a new model system for condensed matter physics. It also has the double identity of an extraordinary conductor and the thinnest isolated membrane. In this talk I will present our results on both of these aspects, such as observation of coherent interference of multply-reflected charge waves, p-n-p junctions in zero and high magnetic fields, symmetry breaking and fractional quantum Hall effect in bilayer graphene, and ripple formation and manipulation on suspneded graphene sheets. I will conclude the talk with a brief discussion on the fascinating prospect of strain-based graphene engineering.
