Brillouin zones


Assuming idealized free electron behaviour in a three-dimensional simple cubic


lattice, calculate the ratio of the energy of an electron at the corner of the first


Brillouin zone to the energy of an electron at the midpoint of a face of the first Brillouin zone.


If a metal has a cubic lattice with parameter of 0.3 nm and its Fermi surface just


touches the Brillouin zone boundary, determine the Fermi energy, the number of


conduction electron states NQ(£) per unit volume, and the density of states D(E)


per unit volume at the Fermi level.
