Characterization of the direct laser-written MoS₂ film

(A and B) Optical images of MoS₂ film on SiO₂/Si substrate after direct laser writing. The high-magnification optical image shown in (B) is taken from the black box shown in (A).

(C) Raman spectrum of locations with and without laser writing obtained from the locations marked in (B).

(D–F) XPS spectra of the film on SiO₂/Si substrate with and without laser writing.

(G and H) Optical images of MoS₂ film on SiO₂/Si substrate before and after rinsing.

(I) AFM image of direct laser writing MoS₂ film.
