Abstract
The electronic properties of SiC nanoribbons are investigated by the first principles calculation. Their atomic structure is assumed to be the same as the structure of graphene nanoribbons, viz., the honeycomb structure. The influences of the width and edge state of the nanoribbons on their density of states and band structures are examined. The result suggests the bandgap of a SiC nanoribbon depends on the geometry of its stable structure rather than whether it is hydrogen-terminated or not.
