Edge decorated SiC nanoribbons with metal: Coexistence of planar tetracoordinate carbon and silicon

We present ab initio calculation evidence of a hitherto unreported one-dimensional nanostructure, where both planar tetracoordinate carbon (ptC) strips and planar tetracoordinate silicon (ptSi) strips can coexist. The host nanostructure for ptC and ptSi strips is the SiC zigzag nanoribbons (SCNRs) whose edges are decorated by transition metal atoms.
