Fig. 4: Raman and EPR spectra of DDT and DDT/MoS2.

a Raman spectra of the DDT overhang and DDT/MoS2 interface of the DDT/MoS2 structure shown in Fig. 2b and d. Black dots represent Raman modes of MoS2. b X-band EPR spectra of DDT, MoS2, and DDT/MoS2 at RT under dark conditions. The magnification of the EPR peak of MoS2 and half-field EPR transition in the range of (c) 275-375 mT and (d) 110-210 mT, respectively.
