Fig. 2

a Raman spectra of FePS3-MoS2 heterojunction (top panel), MoS2 (middle panel) and FePS3 (bottom panel) collected with 532 nm excitation laser and 1800 gr/mm grating. b Optical absorbance of FePS3, MoS2, and the heterojunction, where the junction encompasses the absorption range of both FePS3 and MoS2. c Photoluminescence (PL) spectra of FePS3 and MoS2 individually (with 405 nm excitation laser), as well as at the heterojunction, which showed quenching of PL.
