Plasmons in MoS2 studied via experimental and theoretical correlation of energy loss spectra

“…The 𝜋 and 𝜋 + 𝜎 plasmons in graphene seemed to shift to lower energies due to the disappearance of the bulk plasmon mode in mono-and few layer graphene leaving the surface modes as the prominent signals in the EELS spectra. In later EELS experiments, a novel plasmon mode was observed at ~3eV in doped graphene [13]. There has been a large amount of theoretical and experimental work looking into the different plasmon modes that exist for graphene with different dopant configurations [14,15].…”
