Frictional figures of merit for single layered nanostructures
S. Cahangirov, C. Ataca, M. Topsakal +2
We determined frictional figures of merit for a pair of layered honeycomb nanostructures, such as graphane, fluorographene, MoS and WO moving over each other, by carrying o…
Silicite: the layered allotrope of silicon
Seymur Cahangirov, V. Ongun Ozcelik, Angel Rubio +1
Based on first-principles calculation we predict two new thermodynamically stable layered-phases of silicon, named as silicites, which exhibit strong directionality in the electron…
The atomic structure of the phase of silicene on Ag(111)
Seymur Cahangirov, Veli Ongun Özçelik, Lede Xian +5
The growth of the reconstructed silicene on Ag substrate has been frequently observed in experiments while its atomic structure and formation mechanism i…
Stable two-dimensional dumbbell stanene: a quantum spin Hall insulator
Peizhe Tang, Pengcheng Chen, Wendong Cao +7
We predict from first-principles calculations a novel structure of stanene with dumbbell units (DB), and show that it is a two-dimensional topological insulator with inverted band…
Germanene: a novel two-dimensional Germanium allotrope akin to Graphene and Silicene
M. E. Dávila, L. Xian, S. Cahangirov +2
Using a gold (111) surface as a substrate we have grown in situ by molecular beam epitaxy an atom-thin, ordered, two-dimensional multi-phase film. Its growth bears strong similarit…
