Fig. 1From: Spin- and Valley-Dependent Electronic Structure in Silicene Under Periodic PotentialsTop: schematic of the silicene superlattices. The FM insulators, such as EuO and EuS, on the top of silicene induce the exchange fields in silicene, as proposed for graphene [53]. The metallic gates on the top of FM insulators control the Fermi level locally. Bottom: schematic of the energy spectrum in silicene with and without external fieldsBack to article page
