a, Conductivity σxx of MLG as a function of B and carrier density at 300 K. The measurements are for a Corbino-disk device. The vertical yellow line indicates the NP, and the red lines follow ν = ±2. b, Room-T resistivity for MLG measured in the Hall-bar geometry at three representative B. The traces are shifted for clarity by 0.1 kΩ. The vertical arrows mark ν = ±2.
