For Semiconductor we have terms and definitions in 10 topics. The topics are Automotive, Computer Technology, Electric Power, Energy, Explosives, Music Technology, Science, Solar Energy, Technology and Transistors.

Semiconductor (Automotive)

Substance that acts as an insulator or a conductor, depending upon conditions.

Semiconductor (Computer Technology)

A semiconductor is a substance (usually Silicon doped with Germanium or Arsenic) that selectively conducts electricity. The selection usually occurs by running another current through a different axis. This is the principle of an transistor, and thus of chips as well.

Semiconductor (Electric Power)

Any material that has a limited capacity for conducting an electric current. Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.

Semiconductor (Energy)

Any material that has a limited capacity for conducting an electric current. Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.

Semiconductor (Explosives)

Semiconductor, a solid material ( Solid State Physics) whose electrical conductivity at room temperature lies between that of a conductor and that of an insulator ( Conduction; Insulation). At high temperatures its conductivity approaches that of a metal, and at low temperatures it acts as an insulator. In a semiconductor there is a limited movement of electrons, depending upon the crystal structure of the material used. Incorporation of certain impurities in a semiconductor enhances its conductive properties. The impurities either add free electrons or create holes (electron deficiencies) in the crystal structures of the host substances by attracting electrons. Thus there are two semiconductor types: the n-type (negative), in which the current carriers (electrons) are negative, and the p-type (positive), in which the positively charged holes move and carry the current. Compounds such as indium antimonide, gallium arsenide, and aluminum phosphide are semiconductors. Semiconductors are used in electronic devices such as computers, Photoelectric Cells, Rectifiers, and Transistors.

Semiconductor (Music Technology)

Material / Substance that is at a mid way point between being a conductor and an insulator. This property is invaluable for creating transistors, which need to be capaple of switching between these two states. Examples of semiconductive materials include Silicon (cheap and most widely used) Germanium, and Gallium Arsenide, which is a compound of gallium and arsenic.

Semiconductor (Science)

A solid whose electrical conductivity is between that of a conductor and that of an insulator

Semiconductor (Solar Energy)

Any material that has a limited capacity for conducting an electric current. Generally falls between a metal and an insulator in conductivity. Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.

Semiconductor (Technology)

A substance, commonly silicon or germanium, whose ability to conduct electricity falls between that of a conductor and that of a nonconductor (insulator). The term is used loosely to refer to electronic components made from semiconductor materials.

Semiconductor (Transistors)

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.
