Problem 8

Question:For a diamond crystal structure, determine the atomic packing factor, given that,a = 8R√3

Problem 9

Question: Determine the planar concentration of (100), (101), (111), (020) and (210) plane of both FCC

and BCC structures in terms of lattice parameter.

Problem 10

Question: Copper (Cu) has the FCC crystal structure. Considering the fact that, oxide growth is higher

on a plane which has higher planer concentration, among (100), (110), (111) which plane is more suitable

for oxide growth and why? Radius of one Cu atom on 0.128nm.
