Defect Engineering in 2D Materials: Precise Manipulation and Improved Functionalities
Defect engineering by chemical treatment. TEM image of MoS2 before (a) and after (b) MPS treatment. Scale bar, 1 nm. (c) Typical -Vg characteristics for as-exfoliated (black), TS-treated (blue), and DS-treated monolayer MoS2 at K. Reproduced from . (d) Schematic diagram of carrier recombination and trapping kinetics. (e) Transient response and (f) specific detectivity of as-prepared and H2PP-decorated ReS2. Reproduced from .
