  1. 1. Lecture 3 ETE411 :: Semiconductor
  2. 2. Exercise <ul><li>To calculate the surface density of atoms on a perpendicular plane in a crystal. </li></ul><ul><li>Consider the body-centered cubic structure and the (110) plane shown in Figure. Assume the atoms can be represented as hard spheres with the closest atoms touching reach other. Assume the lattice constant is a, = 5 A. Figure shows how the atoms are cut by the (110) plane. </li></ul>
  3. 5. The Diamond Structure
