Energy Band Structure,structures will be given in Sect. 2.4 and used for the calculation of charge transport in Chaps. 7, 8, while in Chaps. 4, 5, the transport properties will be calculated assuming the simple model of band structure (which is quite a good approximation for most purposes).

Elementary Properties of Semiconductors, called insulators. Metallic conductivity is typically between 10. and 10. (Ω cm)., while typical insulators have conductivities of less than 10. (Ω cm).. Some solids with conductivities between 10. and 10. (Ω cm). are classified as .. However, substances such as alkali-halides whose conductivity is
