AbstractWe investigate the effects of the in-plane biaxial strain and charge doping on the charge density wave (CDW) order of monolayer 1T -TiSe2 by using the first-principles calculations. Our results show that the tensile strain can significantly enhance the CDWorder, while both compressive strain and charge doping (electrons and holes) suppress the CDW instability. The tensile strain may provide an effective method for obtaining higher CDW transition temperature on the basis of monolayer 1T -TiSe2. We also discuss the potential superconductivity in charge-doped monolayer 1T -TiSe2. Controllable electronic phase transition from the CDW state to the metallic state or even the superconducting state can be realized in monolayer 1T -TiSe2, which makes 1T -TiSe2 possess a promising application in controllable switching electronic devices based on CDW.
