Charge and Energy Transport in a Nondegenerate Electron Gas,the conduction band and .. in the valence band (3.1.12). For these distributions, no externally applied electric fields were assumed to be present. Instead, the calculations were based on the assumption of thermal equilibrium.

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

Semiconductor Statistics,ve seen in Fig. 2.8. A discussion of these levels can be confined to the first Brillouin zone. We saw in the last chapter that due to the crystal periodicity, the electron wave functions, which in one dimension are .(.) = .(.) exp (i .), also have to be periodic (..
