1. Copper is a monovalent metal with a density of 8 g/cm3 and an atomic weight of 64.
(a) Calculate the Fermi energy in electron volts at 0°K.
(b) Estimate the width of the conduction band.
2. (a) Calculate the Fermi energy of an alloy of 10% zinc (which is divalent) in copper assuming that the alloy has the same atomic spacing and structure as Cu.
(b) How does the width of the conduction band of the alloy compare to that of copper? The assumption used in (a) is not strictly accurate.
