DEFINITION: A semiconductor is a substance, usually a solid chemical elementor compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current. Its conductancevaries depending on the current or voltage applied to a control electrode, or on the intensity ofirradiation by infrared (IR), visible light, ultraviolet (UV), or X rays.The specific

SEMICONDUCTORS DEFINITION (continued):
properties of a semiconductor depend on theimpurities, or dopants, added to it. An N-type semiconductor carries current mainly in the form ofnegatively-charged electrons,in a manner similar to the conduction of current in a wire. A P-typesemiconductor carries current predominantly as electron deficiencies called holes. A hole has a positive electric charge, equal and opposite to the charge on an electron. Ina semiconductor material, the flow of holes occurs in a direction oppositeto the flow of electrons.Elemental semiconductors include antimony, arsenic, boron, carbon,germanium, selenium,
