The graph shown represents the probability of occupation for an electron in a substance with a uniform density of states (unlike a metal where the density of states is proportional to E1/2). This function can be plotted for several different temperatures. The integral shown is normalized and represents the probability of finding electrons of a certain energy range. What percentage of the electrons are within 10% of the Fermi energy at the various temperatures?  Explain.  Restart.
