• vibronic states of an almost isolated molecule. Here, we use scanning tunneling microscopy and spectroscopy to show that a single layer of MoS2 on Ag(111) exhibits a semiconducting bandgap, which may prevent molecular states from strong interactions with the metal substrate. We show that the lowest

These additional spectroscopic measurements unambiguously reveal that sub-monolayer amounts of Si deposited on MoS2 at room temperature do not reside on top of MoS2, but intercalate between the MoS2 layers.
