3. If the effective mass of electrons in the conduction band are less than the effective mass of holes in the valence band, then where will the Fermi level be located for an intrinsic semiconductor? a. Exactly at the middle of the bandgap c. Below the middle of the bandgap b. Above the middle of the bandgap d. At the edge of the conduction band
