Hydrogen on silicene: like or unlike graphene?
Hydrogenation of free-standing silicene, the two-dimensional allotrope of silicon, is investigated in detail using first-principles methods and compared with the adsorption of H atoms on graphene. Similarly to graphene, chemisorption of a single H atom on silicene induces the formation of a semilocalized state around the adatom, a sharp peak in the density of states at the Fermi level which act...
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 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)....
متن کاملConstruction of 2D atomic crystals on transition metal surfaces: graphene, silicene, and hafnene.
The synthesis and structures of graphene on Ru(0001) and Pt(111), silicene on Ag(111) and Ir(111) and the honeycomb hafnium lattice on Ir(111) are reviewed. Epitaxy on a transition metal (TM) substrate is a pro-mising method to produce a variety of two dimensional (2D) atomic crystals which potentially can be used in next generation electronic devices. This method is particularly valuable in th...
متن کاملStructural, electronic, and optical properties of hybrid silicene and graphene nanocomposite.
Structural, electronic, and optical properties of hybrid silicene and graphene (S/G) nanocomposite are examined with density functional theory calculations. It turns out that weak van der Waals interactions dominate between silicene and graphene with their intrinsic electronic properties preserved. Interestingly, interlayer interactions in hybrid S/G nanocomposite induce tunable p-type and n-ty...
