First-principles prediction of superconducting properties of monolayer 1T′-WS2 under biaxial tensile strain

The superconducting properties of monolayer 1T′-WS 2 under biaxial tensile strain were studied. With the increase of strain, the T c firstly increases and then decreases, with the highest T c of 7.25 K under the biaxial tensile strain of 3%.
