From: Valley polarized quantum Hall effect and topological insulator phase transitions in silicene
Hall (top) and longitudinal (bottom) conductivities as functions of the Fermi energy for 7 meV electric field energy.
T = 2 K, ΔSO = 4 meV and B = 1 T. Black lines correspond to the K valley and red lines to the K′ valley. This situation represents a Hall insulator.
