Question:

Use Equation 8-69 to plot an accurate graph of n_FD(E) /V for electrons whose Fermi energy is 4.8 eV from E = 4.5 eV to E = 5.1 eV at T = 300 K. Determine from the graph the number of electrons per unit volume just below the Fermi energy that can move to states just above the Fermi energy.
