Electronic properties of twisted armchair graphene nanoribbons
We study the effect of twist on the electronic structure of H-terminated armchair graphene nanoribbons, for both relaxed and unrelaxed unit cell size. We investigate the band gap change as a function of the twist angle for different ribbon widths. In the case of unrelaxed unit cell size, the band gap closes for smaller twist angles as opposed to relaxed unit cell size. We calculate strain energ...
متن کاملMöbius and twisted graphene nanoribbons: stability, geometry, and electronic properties.
Results of classical force field geometry optimizations for twisted graphene nanoribbons with a number of twists N(t) varying from 0 to 7 (the case N(t)=1 corresponds to a half-twist Möbius nanoribbon) are presented in this work. Their structural stability was investigated using the Brenner reactive force field. The best classical molecular geometries were used as input for semiempirical calcul...
متن کاملInterfacial Properties of Bilayer and Trilayer Graphene on Metal Substrates
One popular approach to prepare graphene is to grow them on transition metal substrates via chemical vapor deposition. By using the density functional theory with dispersion correction, we systematically investigate for the first time the interfacial properties of bilayer (BLG) and trilayer graphene (TLG) on metal substrates. Three categories of interfacial structures are revealed. The adsorpti...
متن کاملStructural and electronic properties of bilayer and trilayer graphdiyne.
Stimulated by the recent experimental synthesis of a new layered carbon allotrope-graphdiyne film, we provide the first systematic ab initio investigation of the structural and electronic properties of bilayer and trilayer graphdiyne and explore the possibility of tuning the energy gap via a homogeneous perpendicular electric field. Our results show that the most stable bilayer and trilayer gra...
متن کاملElectronic properties of twisted bilayer nanoribbons
We study the band structure, density of states, and spatial localization of edge states in twisted bilayer graphene nanoribbons. We devise these ribbons by cutting a stripe of commensurate twisted bilayer graphene along a direction with a maximum number of zigzag edge atoms. Due to the spatially inhomogeneous interlayer coupling, edge states stemming from regions with AB stacking are closer to ...
