Static charging of graphene and graphite slabs
Mehmet Topsakal, Salim Ciraci
The effect of external static charging of graphene and its flakes are investigated by using first-principles calculations. While the Fermi level of negatively charged graphene rise…
Long ranged interactions in carbon atomic chains
S. Cahangirov, M. Topsakal, S. Ciraci
Based on first-principles calculations we revealed fundamental properties of infinite and finite size monatomic chains of carbon atoms in equilibrium and under an applied strain. D…
Current-voltage (I-V) characteristics of armchair graphene nanoribbons under uniaxial strain
Mehmet Topsakal, V. M. Kemal Bagci, Salim Ciraci
The current-voltage (I-V) characteristics of armchair graphene nanoribbons under a local uniaxial tension are investigated by using first principles quantum transport calculations.…
A First-Principles Study of Defects and Adatoms in Silicon Carbide Honeycomb Structures
E. Bekaroglu, M. Topsakal, S. Cahangirov +1
We present a study of mechanical, electronic and magnetic properties of two dimensional (2D), monolayer of silicon carbide (SiC) in honeycomb structure and its quasi 1D armchair na…
Armchair nanoribbons of silicon and germanium honeycomb structures
S. Cahangirov, M. Topsakal, S. Ciraci
We present a first-principles study of bare and hydrogen passivated armchair nanoribbons of the puckered single layer honeycomb structures of silicon and germanium. Our study inclu…
