Homework Help: Lattice Planes

  1. Feb 20, 2015 #1
    1. The problem statement, all variables and given/known data
    Prove that the lattice planes with the greatest densities of points are the {111} planes in a fcc bravis lattice and the {110} planes in a bcc bravis lattice.

    2. Relevant equations
    d/v=points per unit area where d is the spacing of planes and v is the unit volume.

    3. The attempt at a solution
    In the fcc case
    [tex] d=\frac{2\pi}{hb_1+kb_2+lb_3}\\
    Which is in terms of the reciprocal space. So we simply need to maximize this value. Does this immediately tell us it is in the {111} miller index because the reciprocal is given in terms of 3 coordinates?
