 In this chapter, we will:
-■ Describe three classifications of solids—amorphous 非晶体, polycrystalline 多晶体, and single crystal.
-■ Discuss the concept of a unit cell.
-■ Describe three simple crystal structures and determine the volume and surfacedensity of atoms in each structure.
-■ Describe the diamond crystal structure.
-■ Briefly discuss several methods of forming single-crystal semiconductor materials.
