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.
