Introduction to the Physics of Silicene and other 2D Materials
S. Cahangirov, H. Sahin, G. Le Lay +1
This concise book offers an essential introduction and reference guide for the many newcomers to the field of physics of elemental 2D materials. Silicene and related materials are…
2D vibrational properties of epitaxial silicene on Ag(111) probed by in situ Raman Spectroscopy
Dmytro Solonenko, Ovidiu D. Gordan, Guy Le Lay +2
The two-dimensional silicon allotrope, silicene, could spur the development of new and original concepts in Si-based nanotechnology. Up to now silicene can only be epitaxially synt…
Polyyne Electronic and Vibrational Properties under Environmental Interactions
M. Wanko, Seymur Cahangirov, Lei Shi +6
Recently, the novel system of linear carbon chains inside of double-walled carbon nanotubes has extended the length of hybridized carbon chains from 44 to thousands of atoms…
Bilayer SnS: Easy-tunable Stacking Sequence by Charging and Loading Pressure
C. Bacaksiz, S. Cahangirov, A. Rubio +3
Employing density functional theory-based methods, we investigate monolayer and bilayer structures of hexagonal SnS, which is recently synthesized monolayer metal dichalcogen…
Confined linear carbon chains: A route to bulk carbyne
Lei Shi, Philip Rohringer, Kazu Suenaga +6
The extreme instability and strong chemical activity of carbyne, the infinite sp1 hybridized carbon chain, are responsible for its low possibility to survive in ambient conditions.…
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…
