The effect of strain on the zigzag and armchair phosphorene nanoribbon

Abstract

Abstract In this work, the band structure and electronic properties of different nanoribbons of phosphorene along two typical crystal directions of armchair (AM) and zigzag (ZZ) were investigated under compression and tensile strain by density functional theory. The results were compared to the band structure and electronic properties of phosphorene monolayer at similar conditions. The electronic properties of armchair nanoribbons revealed to be resistant to tensile strain in the direction of the armchair, consistent to phosphorene monolayer, but they undergo band structure change due to the applied compression strain at armchair direction. By comparing the effects of strain on the zigzag nanoribbon and phosphorene monolayer, it was found that the zigzag direction neither tolerates the tensile strain nor resists compression strain.
