1. (25 points) Explain the following in terms of band structure of solids. (a) (5 points) Sodium is a monovalent solid, and it is a metal. (b) (5 points) Calcium is a divalent solid, and it is a metal. (c) (5 points) Diamond is a 4-valent solid, and it is an insulator. Its band gap is 5.5eV. (d) (5 points) Silicon and Germanium are 4-valent solids, and they are semiconduc- tors. Their band gaps are 1.leV and 0.67eV, respectively. (e) (5 points) Diamond is transparent. 2
