From: Electrically controllable sudden reversals in spin and valley polarization in silicene
(a–d) Contour plots of the transmission probability as a function of incident angle and external gate voltage. (e,f) Dispersion relations of the electrons in silicene modulated by the ferromagnetic superlattice. The colour regions are values of Vg and ky which have propagating electron states in the superlattice (states with real qSL). Blue is for up spin electrons and red is for down spin electrons. The parameters are the same as that of Fig. 3.
