Calculate values for the Fermi function f(E) at 300 K and plot vs. energy in eV as in Fig. 3–14. Choose EF = 1 eV and make the calculated points closer together near the Fermi level to obtain a smooth curve. Notice that f(E) varies quite rapidly within a few kT of EF. Show that the probability that a state ΔE above EF is occupied is the same as the probability that the state ΔE below EF is empty
