Abstract

Two-dimensional monolayer transition metal dichalcogenides have attracted a lot of attention owing to their excellent physical properties. The significant polarization field induced by external strain within two-dimensional piezoelectric semiconductor materials can effectively regulate the properties of the materials. In this article, the edge-state of MoS₂/WS₂ lateral heteroribbon has been theoretically investigated by three-orbital tight-binding model. And the piezotronic effect on the edge state is also studied. The external in-plane stress can induce a metallic-to-semiconducting phase transition. This study offers an effective way to module the electric properties of lateral heterostructure.
