Figure 3From: Dirac fermion heating, current scaling, and direct insulator-quantum Hall transition in multilayer epitaxial grapheneMagnetoresistivity measurements ρ xx (B) at driving currents I. The lattice temperature is constantly fixed at T ≈ 1.9 K. From top to bottom: I = 2, 3, 5, 7, 8.5, 10, 20, 30, 50, 70, 85, 100, 125, 150, 200, and 225 μA, respectively.Back to article page
