A number of devices used in the electronics industry have, over the years, become classified as non-linear. These include such components as the thermistor (a resistor that is non-linear with respect to temperature and current), and the varistor (a non-linear resistor with respect to voltage). These devices, the materials from which they are fabricated and their applications are described in this chapter together with other non-linear semiconducting materials that are still in the early stages of development into useful electronic components.
