111 surface of an fcc structure

#1 Post by smanos » Tue Nov 06, 2012 2:08 pm

Hi everybody

I am trying to create a 111 surface from an fcc lattice structure. I can do 100 and 110 easily but in 111 things get tough for me because the unit shell is cannot be orthogonal (Y-X=60 degrees). Can someone make a suggestion on how to obtain the correct coordinates of the atoms in that case?

Hint: you can compute the distance between (111) planes from a/sqrt(h^2+k^2+l^2). Also, fcc has stacking sequence ABCABCABC and you can look up the relative displacements of atoms on adjacent (111) planes.
