Hydrogenated grain boundaries in graphene
W. H. Brito, R. Kagimura, R. H. Miwa
We have investigated by means of first principles calculations the structural and electronic properties of hydrogenated graphene structures with distinct grain boundary defects. Ou…

Surface dangling bond states and band-lineups in hydrogen-terminated Si, Ge, and Ge/Si nanowires
R. Kagimura, R. W. Nunes, H. Chacham
We report an ab initio study of the electronic properties of surface dangling-bond (SDB) states in hydrogen-terminated Si and Ge nanowires with diameters between 1 and 2 nm, Ge/Si…

Structures of Si and Ge nanowires in the sub-nanometer range
Ricardo Kagimura, Ricardo W. Nunes, Helio Chacham
We report an ab-initio investigation of several possible Si and Ge pristine nanowires with diameters between 0.5 and 1.2 nm. We considered nanowires based on the diamond structure,…
