1. A plane in simple cubic crystal is described as (133) plane. What are the intercepts on the a, b, and c axes. Sketch the plan.
2. The volume density of atoms for a bcc lattice is 5 x 1026 m-3. Assume that the atoms are hard spheres with each atom touching its nearest neighbors. Determine the lattice constant and effective radius of the atom.
3. The lattice constant of a body centered cubic unit cell is a=4.85 oA. Determine the volume density of atoms. (Hints: Volume density=number of unit cell atoms/unit cell volume).
4. Determine volume density of germanium atoms in germanium semiconductor. The lattice constant of germanium is a=6.66°A.
