K-band ESR spectra observed at 1.8 K using P _μ ~ 25 nW for B//n on three 2D MoS₂/SiO₂/(100)Si entities, showing the observation of the LM1 signal (at g ~ 2.0014 in the process-a samples). The signal at g = 1.99875 stems from a co-mounted Si:P marker sample, also used for field axis alignment of the spectra. The spectra have been normalized to equal Si:P marker intensity and sample area
