We demonstrate electromechanical properties of monolayer SnX2 (X = Se, Te) with 1T structure as a function of charge doping using first-principles methods. We indicate that the monolayer SnSe2 shows a semiconductor-metal transition for the case of heavy electron doping, while SnTe2 retains the metallic properties under both electron and hole dopings. The actuation strain of SnX2 in the case of electron doping is significantly higher than those of hole doping. In addition, we also compute the ideal strength and ideal strain of the monolayer SnX2 under charge doping.
