Epitaxial Graphene Nanoribbons on Bunched Steps of a 6H-SiC(0001) Substrate: Aromatic Ring Pattern and Van Hove Singularities
M. Ridene, T. Wassmann, E. Pallecchi +3
We report scanning tunneling microscopy and spectroscopy investigation of graphene nanoribbons grown on an array of bunched steps of a 6H-SiC(0001) substrate. Our scanning tunnelin…
Structure and stability of graphene nanoribbons in oxygen, carbon dioxide, water, and ammonia
Ari P. Seitsonen, A. Marco Saitta, Tobias Wassmann +2
We determine, by means of density functional theory, the stability and the structure of graphene nanoribbon (GNR) edges in presence of molecules such as oxygen, water, ammonia, and…
Clar's Theory, STM Images, and Geometry of Graphene Nanoribbons
Tobias Wassmann, Ari P. Seitsonen, A. Marco Saitta +2
We show that Clar's theory of the aromatic sextet is a simple and powerful tool to predict the stability, the π-electron distribution, the geometry, the electronic/magnetic structu…
Structure, Stability, Edge States and Aromaticity of Graphene Ribbons
Tobias Wassmann, Ari P. Seitsonen, A. Marco Saitta +2
We determine the stability, the geometry, the electronic and magnetic structure of hydrogen-terminated graphene-nanoribbons edges as a function of the hydrogen content of the envir…
