semiconductor
A substance with electrical properties intermediate between a good conductor and a good insulator
a material that has much lower resistance to the flow of electrical current in one direction than in another Diodes, transistors, and many photovoltaic cells contain semiconductive materials
An element (e g , silicon and germanium) whose electrical conductivity lies between that of conductors (copper) and insulators (glass) Has relatively high resistance in a pure state and much lower resistance when small amounts of impurities are added
A material that has a resistance characteristic between that of insulators and conductors
A material (such as silicon) which can be altered to either conduct electrical current or block its passage Microchips are typically fabricated on semiconductor materials such as silicon, germanium, or gallium arsenide
In wire industry terminology, a material possessing electrical conductivity that falls somewhere between that of conductors and insulators Usually made by adding carbon particles to an insulator Not the same as semiconductor materials such as silicon, germanium, etc
A substance that exhibits properties of a conductor but with higher resitivities If a semiconductor has a small amount of a foreign substance added to it (doping), the original material can become a normal conductor Silicon and germanium are natural semiconductors
An element, such as silicon, that is intermediate in electrical conductivity between conductors and insulators, through which conduction takes place by means of holes and electrons
A material that is neither a good electrical conductor nor a good electric insulator
a solid material such as silicon or germanium with conductive capacity intermediate between an insulator and a good conductor such as soft copper Both active and passive elements may be formed on a single semi-conductor crystal
A substance that does not conduct electricity at low temperatures but does so at higher temperatures
a substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities
material which can conduct electricity better than an insulator, but not as well as a conductor
A substance or material that conducts electricity better than an insulator but not as well as a conductor Examples of semiconductors include silicon and germanium
Any material that has a limited capacity for conducting an electric current Any class of solids whose electrical CONDUCTIVITY is between that of a CONDUCTOR and that of an INSULATOR in being nearly as great as that of a metal at high temperatures and nearly absent at low temperatures Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process
A material like silicon or germanium in which the valence band and the conduction band are separated by a small (forbidden) energy gap Such materials have some of the properties of a good electrical conductor-in which the energy gap is zero-and some of the properties of an insulator-in which the gap is very large
A material that conducts more than an insulator but less than a conductor Some semiconductors conduct at some times but not at others Some common semiconductors are silicon and germanium Transistors are made out of semiconductor crystals
1) A material which conducts more than an insulator but less than a conductor 2) Any device, such as a transistor, which is mainly made from semiconductor material
A semiconductor is a substance used in electronics whose ability to conduct electricity increases with greater heat. a substance, such as silicon, that allows some electric currents to pass through it, and is used in electronic equipment. Class of crystalline solids with electrical conductivity between that of a conductor and an insulator. Such materials can be treated chemically to allow transmission and control of an electric current. Semiconductors are used in the manufacture of electronic devices such as diodes, transistors, and integrated circuits. Intrinsic semiconductors have a high degree of chemical purity, but their conductivity is poor. Extrinsic semiconductors contain impurities that produce much greater conductivity. Some common intrinsic semiconductors are single crystals of silicon, germanium, and gallium arsenide; such materials can be converted into the technologically more important extrinsic semiconductors by addition of small amounts of impurities, a process called doping (see dopant). Advances in semiconductor technology in recent years have gone hand in hand with increased operational speed in computers
