1. A silicon sample is doped with donor atoms/cm³at room temperature (300K). The intrinsic carrier density in Si is 9.65x10⁹

(b) Find the Fermi level. (10%) (Note: Sketch the band diagram and mark E_c, E_v, E_F and E_i； indicate clearly the location of the Fermi level with respect to intrinsic level.)
