Ferroelectrics,we shall deal with dielectrics for which this relationship exhibits hysteresis effects. Since the dielectric behavior of these materials is in many respects analogous to the magnetic behavior of ferromagnetic materials, they are called ferroelectric solids, or simply ferroelectrics. A ferroelectric

The Conductivity of Metals,of insulators is given in Sec. 11-9. Within the allowed space it did not seem possible to discuss superconductivity, thermoelectric, galvanomagnetic, and thermomagnetic effects, although a simplified derivation of the Hall effect is included as the last section.

Nonpolar Semiconductors,siderably smaller than that of metals, and on the other hand, is much larger than that of “insulators.” Furthermore, the conductivity increases with temperature, in contrast with the behavior of metals at normal temperatures. The number of current carriers per unit volume in a semiconductor is in ge

Luminescence, the visible or near-visible region of the spectrum. This phenomenon is called luminescence, with the understanding that this term does not include the emission of black-body radiation, which obeys the laws of Kirchhoff and Wien. Luminescent solids are usually referred to as phosphors.
