Kittel problem 9.4Show for a simple square lattice in two dimensions that the kinetic energy of a free electron at a corner of the first zone is higher than that of an electron at the midpoint of a side face of the zone by a factor of 2. What is the corresponding factor for a simple cubic lattice in three dimensions? What bearing might this result have on the conductivity of divalent metals? |
