Fermi - The Fermi energy of a (n-doped) semiconductor is typically rather close to the band edge. In fact, by controlling the doping, it can be made it as close to the band edge as we want. On the other hand, in metal, where the conduction band is partially filled with electrons, the Fermi energy is necessarily quite big.
