Electrically tunable magnetoplasmons in a monolayer of silicene or germanene.
We theoretically study electrically tunable magnetoplasmons in a monolayer of silicene or germanene. We derive the dynamical response function and take into account the effects of strong spin-orbit coupling (SOC) and of an external electric filed E(z) perpendicular to the plane of the buckled silicene/germanene. Employing the random-phase approximation we analyze the magnetoplasmon spectrum. Th...
متن کاملBeyond graphene: stable elemental monolayers of silicene and germanene.
Two-dimensional materials are one of the most active areas of nanomaterials research. Here we report the structural stability, electronic and vibrational properties of different monolayer configurations of the group IV elemental materials silicene and germanene. The structure of the stable configuration is calculated and for planar and low (<1 Å) atomic buckling configurations, analysis of the ...

متن کاملIntrinsic magnetism and spontaneous band gap opening in bilayer silicene and germanene.
It has been long sought to create magnetism out of simple non-magnetic materials, such as silicon and germanium. Here we show that intrinsic magnetism exists in bilayer silicene and germanene with no need to cut, etch, or dope. Unlike bilayer graphene, strong covalent interlayer bonding formed in bilayer silicene and germanene breaks the original π-bonding network of each layer, leaving the unb...
متن کاملStability and Electronic Properties of Two-Dimensional Silicene and Germanene on Graphene CHIH-PIAO CHUU,
Submitted for the MAR14 Meeting of The American Physical Society Stability and Electronic Properties of Two-Dimensional Silicene and Germanene on Graphene CHIH-PIAO CHUU, YONGMAO CAI, C.-M. WEI, M.-Y. CHOU, Academia Sinica — Recently, there have been experimental attempts to synthesize silicene, a two-dimensional (2D) graphene-like form of silicon on metal surfaces such as Ag(111) and Ir(0001)....
