摘要：Graphene, a two - dimensional single atomic layer of carbon, has recently emerged as a new model system for condensed matter physics, as well as a promising candidate for electronic materials. Here I will present our results on transport measurements in bilayer and trilayer graphene devices with mobility as high as 400,000 cm2/Vs. We demonstrate the presence of an intrinsic gapped state in bilayer and trilayer graphene at the charge neutrality point, a "new" spectroscopy technique for measuring the Landau level gaps, the distinct competing states at filling factor 2 and crossing between symmetry-broken Landau levels. Our results underscore the fascinating many-body physics in these 2D membranes.
