7. Estimate the fraction of electrons excited above the Fermi level at room temperature for Cu and Na. 8. Calculate the ratio of electrons to lattice heat capacities for Cu at T=0.3∘,4∘,20∘, 77∘, and 300∘K. The lattice heat capacity of Cu is given in Fig. 3.10.
Fig. 3.10 Specific heat of copper versus temperature. The dots represent experimental values, and the curve is given by the Einstein expression.
