Abstract

Graphene and single layer silicon (silicene) are supposed to have excellent electronic properties. A theoretical study on zigzag silicon and silicon mono-oxide nanoribbons has been performed in honeycomb structures within the framework of density functional theory (DFT). There exist theoretical studies on mono-layer buckled silicon but not on silicon mono-oxide. In this paper we have tried to present a comparative study of the structural, electronic and transport properties of zigzag silicene nanoribbon and zigzag silicon mono-oxide nanoribbon. A first principle approach has been made for the structural optimization of silicene and silicon mono-oxide nanoribbon followed by electronic properties study viz. density of states, charge densities and finally transports properties like transmission energy and I-V characteristics prominently.
