4 The lattice constant of a single crystal is 4.50 A. Calculate the surface density of atoms (# per cm) on the following planes: (i) (100), (ii) (110), (iii) (111) for each of the following lattice structures: (a) simple cubic, (b) body-centered cubic, and (c) face-centered cubic. 5 Determine the surface density of atoms for silicon on the (a) (100) plane. (b) (110) plane, and (c) (111) plane. 6 Consider a face-centered cubic lattice. Assume the atoms are hard spheres with the surfaces of the nearest neighbors touching. Assume the radius of the atom is 2.25 A. (a) Calculate the volume density of atoms in the crystal. (b) Calculate the distance between ncarest (110) planes. (c) Calculate the surface density of atoms on the (110) plane.
