(a) Assume that a metal has a bee lattice with a lattice constant a = 58, and that each atom has one valence electron which becomes a conduction electron in the solid. What is the concentration of conduction electrons in m3? (b) Using the free electron model, derive an explicit expression for the Fermi energy Es in terms of the number density of electrons in terms of electron concentration n). (c) Estimate the Fermi energy Ef for the metal from part (a) in eV. = (h = 6.62x10-34 J.s; c= 3.0x108 m/s; k= 1.38x10-23 J/K = 8.6x10-5 eV/K; me = 9.1x10-31 kg; 1 eV = 1.6x10-191)
