The electron density corresponding to a Fermi energy which is 0.3 eV above the intrinsic energy is calculated from n(EF - Ei = 0.3 eV) = ni exp(0.3/0.02584),from which the hole density is obtained using: p = ni2/n,The electron density corresponding to a Fermi energy which is 0.3 eV below the conduction band edge is calculated from, n(EC - EF = 0.3 eV) = NC exp(-0.3/0.02584), from which the hole density is obtained using: p = ni2/n, The corresponding values are listed in the table below:
