Electronic properties of phosphorene nanoribbons

Abstract

We focus on the electronic properties calculations of phosphorene nanoribbons and multilayer phosphorene using tight-binding model. Our results show that multilayer phosphorene band gaps decreases with increasing the number of layers. We found that zigzag phosphorene nanoribbons are metals, regardless of the ribbon width while armchair phosphorene nanoribbons are semiconductors with indirect bandgaps to variation of the ribbon width.
