The structural and electronic properties of graphane nanoribbons, i.e., completely hydrogenated graphene nanoribbons, were investigated by means of density functional theory computations. Because all the carbon atoms are sp 3 -hybridized and saturated with hydrogen atoms, graphane nanoribbons present completely different electronic properties compared with graphene nanoribbons. Independent of the chirality, graphane nanoribbons are always wide-band-gap semiconductors. Graphane nanoribbons have favorable formation energies, and can be realized by hydrogenating graphene nanoribbons or cutting experimentally available graphanes. These one-dimensional hydrocarbons will find their potential applications to nanotechnology after further band structure tuning.
