Fig. 5From: Spin- and Valley-Dependent Electronic Structure in Silicene Under Periodic Potentials(a–d) Velocity versus potential U, and the parameters are set as h=20.0 meV and Δ z =7.8 meV. The black, red, blue, and green solid curves are the velocities v0x, v1x, v2x, and v3x, respectively. The black, red, blue, and green dashed curves are the velocities v0y, v1y, v2y, and v3y, respectivelyBack to article page
