Semiconducting 2D transition metal dichalcogenides (2D TMDs) with tunable electronic properties are a fundamental prerequisite for the development of next generation advanced electronic/optoelectronic devices. However, controllable and quasi-continuous tuning carrier polarity of monolayered MoS2 ranging from intrinsic n-type to p-type via ambipolarity still remains a challenge. Herein, quasi-continuous tailoring of carrier polarity of monolayered MoS2 through substitutional doping of molybdenum (Mo) with vanadium (V) atoms is presented. Atomic distribution in real space characterized by spherical aberration-corrected scanning transmission electron microscopy (Cs-STEM) reveals that the V atoms randomly substitute Mo in monolayered MoS2, and its doping concentration can be tuned in a wide range from 0.7 to approximate to 10 at.%. Electrical measurements confirm that the carrier polarity of the monolayered MoS2 can be tuned from intrinsic n-type to p-type via ambipolarity depending on the V doping degree, consistent with the density functional theory calculations. Moreover, this doping strategy is demonstrated to extend to other monolayered 2D TMDs by using MoSe2 as a model material, owing to a good universality.
