Intrinsic polarization has been demonstrated in layered structures to reduce the energy gap. Here we demonstrate that strain-induced polarization can increase energy gap and induce a metallic-to-semiconducting phase transition in zigzag nanoribbons of single-layered transitionmetal dichalcogenides, such as MoS2, MoSe2, WS2 and WSe2. This study provides a guidance for designing quantum piezotronic devices. PACS numbers: 73.20.At, 73.43. Nq, 77.22.Ej
