Magnetic Phases of Graphene Nanoribbons under Potential Fluctuations
H. U. Özdemir, A. Altıntaş, A. D. Güçlü
We investigate the effects of long-range potential fluctuations and electron-electron interactions on electronic and magnetic properties of graphene nanoribbons with zigzag edges u…
Wigner crystallization at graphene edges
A. D. Güçlü
Using many-body configuration interaction techniques we show that Wigner crystallization occurs at the zigzag edges of graphene at surprisingly high electronic densities up to $0.8…
Electronic and Magnetic Properties of 1T-TiSe2 Nanoribbons
H. D. Ozaydin, H. Sahin, J. Kang +2
Motivated by the recent synthesis of single layer TiSe2 , we used state-of-the-art density functional theory calculations, to investigate the structural and electronic properties o…
Ag and Au Atoms Intercalated in Bilayer Heterostructures of Transition Metal Dichalcogenides and Graphene
F. Iyikanat, H. Sahin, R. T. Senger +1
The diffusive motion of metal nanoparticles Au and Ag on monolayer and between bilayer heterostructures of transition metal dichalcogenides and graphene are investigated in the fra…
Vacancy Formation and Oxidation Characteristics of Single Layer TiS3
F. Iyikanat, H. Sahin, R. T. Senger +1
The structural, electronic, and magnetic properties of pristine, defective, and oxidized monolayer TiS3 are investigated using first-principles calculations in the framework of den…
