Summary
In this chapter, we studied more theories of band structure calculation and semiclassical description of Bloch electrons. We first introduced orthogonalized plane wave method for expanding the periodic part of the Bloch functions and discussed pseudopotential method and κ · p effective mass theory as practical alternative ways of including the effects of periodic symmetry of crystal potential. Then, the semiclassical wave packet picture is discussed to describe the motion of the Bloch electrons in a given band. In addition, ideas of effective mass and hole are shown to be convenient in describing the behavior of band electrons.
