A silicon material with Nc = 2.8 x 1019 cm 3 , Nv = 1019 cm-3 and intrinsic concentration (theoretical) of 1.5 x 1010 cm 3 is purchased from the market. You wanted to verify this given value of intrinsic concentration in your lab at room temperature. Experiments have shown that the silicon material has a band-gap of 1.1 eV and it is found that the Fermi energy level is 0.85 eV below the conduction band and 0.25 eV above the valence band. Determine the equilibrium concentration of holes and electrons and estimate the % deviation between the theoretical and

experimental values of the intrinsic concentration.
