A cube of copper has edges 1.50 mm long. Calculate the number of electron quantum states in this cube whose energies are in the range 3.75 eV to 3.77 eV.
What is the Fermi energy of the copper?
What is the Fermi temperature of the copper?
What is the ratio of the density of states for electrons at 2.7 eV and at 0.27 eV?
