(Kittel 7.4) Chemical potential versus temperature. Explain graphically why the initial curvature of u versus T is upward for a fermion gas in one dimension and downward in three dimensions (Figure 7.7). Hint: The D, (e) and D3(e) curves are different, where D, is given in Problem 1. It will be found useful to set up the integral for N, the number of particles, and to consider from the graphs the behavior of the integrand between zero temperature and a finite temperature.

4. (Kittel 7.4) Chemical potential versus temperature. Explain graphically why the
initial curvature of u versus 7 is upward for a fermion gas in one dimension and
downward in three dimensions (Figure 7.7).
Hint: The D₁(e) and D, (e) curves are different, where D, is given in Problem 1. It
will be found useful to set up the integral for N, the number of particles, and to
consider from the graphs the behavior of the integrand between zero temperature and
a finite temperature.
