comment Why do we use the massive dirac fermion model for MoS2?
They mentioned two d-states on the Mo, but your tight binding model only consider a single state on Mo, I think that is the why you can not obtain a Dirac model (which would require at least two states in 2D).

comment Why isn't doped silicon a strongly correlated electron system?
@Xcheckr More itinerancy and better screening is just part of the story. The most important point to me is that Si is a fully filled band insulator, instead of a half-filled Mott insulator (or a partially filled orbital selective Mott insulator). The electron filling is important, because a fully filled band insulator effectively has no low-energy degrees of freedom from the electron sector, but strong correlation basically means a lot of different low-energy degrees of freedoms inter-winded together, which can not be realized with a band insulator.
