a SEM image of the as-grown Fe:MoS2 monolayer. Scale bar = 4 µm. b Schematic top and side view of the monolayer. The green, blue, and red spheres are sulfur, molybdenum and iron atoms, respectively. c Contrast-corrected STEM image of the as-grown Fe:MoS2 monolayer. Scale bar = 1 nm. d STEM intensity spectra of the selected area, where the Fe atom exhibits ∼40% lower intensity. Temperature-dependent PL from (e) as-grown MoS2 (f) Fe:MoS2. All PL spectra are taken under 100 µW pump power.
