These materials have a negative temperature coefficient of resistivity and an energy bandgap below four electron volts.
These materials have a negative temperature coefficient of resistivity and an energy bandgap below four electron volts. Depending on whether their impurities are acceptors or donors, they are classified as p-type or n-type, with the p-type's main carrier modeled as holes rather than electrons. The introduction of impurities into them is known as doping, and the best known examples of these materials are germanium and silicon. Name these materials that can act as either insulators or conductors often used in microchips.
