Surface density.

  1. Jan 23, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate the surface density of atoms on (111) and (110) planes for the following crystal structure.
    a) simple cubic, b) body-centered cubic, c)face-centered cubic. Assume the lattice constant is x.

    2. Relevant equations

    well, from reading my lecture notes the general formula for surface density is (#atoms/cm2) . However, the notes doesnt seem to really help as the answer is really way off.

    3. The attempt at a solution

    Help plz :(
