Fig. 4: Room temperature Raman spectra of mechanically exfoliated MoS2 ML before and after implantation.

From: Low-energy Se ion implantation in MoS2 monolayers

Fig. 4

The implantation conditions were with 80Se+ at 20 eV at the fluence of 0.8 · 1014 cm−2. The spectra were acquired with a 532 nm laser excitation. Lines in the spectra are labeled with the vibrational modes that they originate from. E′ and A′ are vibrational modes of MoS2.
