Energy Band Structure

Part of the Springer Study Edition book series (SSE)

Abstract

The “energy band structure” is the relation between energy and momentum of a carrier in a solid. For an electron in free space the energy is proportional to the square of the momentum. The factor of proportionality is 1/2m. where mo is the free electron mass. In the “simple model of band structure” the same relation between energy and momentum is assumed except that mo is replaced by an “effective mass” m. This may be larger or smaller than mo. Why this is so will be seen later in this chapter. Quite often the band structure is more complex and can be calculated even with electronic computers only semiempirically. A short description of some typical band structures will be given in Chap.2d and used for the calculation of charge transport in Chap. 7 and 8 while in Chap. 4 and 5 the transport properties will be calculated assuming the simple model of band structure (which is quite a good approximation for most purposes).
