Figure 1

Honeycomb lattice structure of silicene.

Due to the large ionic radius of silicon the lattice is buckled. The A and B sublattices are shifted by a distance of 2l perpendicular to the silicene sheet to generate a staggered potential in the perpendicular electric field (Ez). We apply a magnetic field (B) perpendicular to the silicene sheet in order to study the valley polarized quantum Hall effect.
