Monitoring of band gap and magnetic state of graphene nanoribbons through vacancies
M. Topsakal, E. Akturk, H. Sevincli +1
Using first-principles plane wave calculations we predict that electronic and magnetic properties of graphene nanoribbons can be affected by defect-induced itinerant states. The ba…
Light Transition Metal Monatomic Chains
C. Ataca, S. Cahangirov, E. Durgun +2
In this paper we investigated structural, electronic and magnetic properties of 3d (light) transition metal (TM) atomic chains using first-principles pseudopotential plane wave cal…
Half-metallic silicon nanowires
Engin Durgun, Deniz Cakir, Nurten Akman +1
From first-principles calculations, we predict that transition metal (TM) atom doped silicon nanowires have a half-metallic ground state. They are insulators for one spin-direction…
Ab-initio electron transport calculations of carbon based string structures
S. Tongay, R. T. Senger, S. Dag +1
First-principles calculations show that monatomic strings of carbon have high cohesive energy and axial strength, and exhibit stability even at high temperatures. Due to their flex…
Chiral single-wall gold nanotubes
R. T. Senger, S. Dag, S. Ciraci
Based on first-principles calculations we show that gold atoms can form both free-standing and tip-suspended chiral single-wall nanotubes composed of helical atomic strands. Free-s…
