Modification of electronic, magnetic structure and topological phase of bismuthene by point defects

Yelda Kadioglu, Sevket Berkay Kilic, Salih Demirci +3

This paper reveals how electronic, magnetic structure and topological phase of 2D, single-layer structures of bismuth are modified by point defects. We first showed that free stand…

High-performance planar nanoscale dielectric capacitors

V. Ongun Özçelik, S. Ciraci

We propose a model for planar nanoscale dielectric capacitor consisting of a single layer, insulating hexagonal boron nitride (BN) stripe placed between two metallic graphene strip…

Adsorption of Group-IV Elements on Graphene, Silicene, Germanene, Stanene: Dumbbell Formation

V. Ongun Özçelik, D. Kecik, E. Durgun +1

Silicene and germanene derivatives constructed from periodic dumbbell units play a crucial role in multilayers of these honeycomb structures. Using first-principles calculations ba…

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…

New Phases of Germanene

V. Ongun Özçelik, E. Durgun, S. Ciraci

Germanene, a graphene like single layer structure of Ge, has been shown to be stable and recently grown on Pt and Au substrates. We show that a Ge adatom adsorbed to germanene push…
