sem·i·con·duc·tor

(sĕm′ē-kən-dŭk′tər, sĕm′ī-)
n.
1. Any of various solid crystalline substances, such as germanium or silicon, having electrical conductivity greater than insulators but less than good conductors, and used especially as a base material for microchips and other electronic devices.
2. An integrated circuit or other electronic component containing a semiconductor as a base material.

sem′i·con·duct′ing adj.

semiconductor

(ˌsɛmɪkənˈdʌktə)
n
1. (General Physics) a substance, such as germanium or silicon, that has an electrical conductivity that increases with temperature and is intermediate between that of a metal and an insulator. The behaviour may be exhibited by the pure substance (intrinsic semiconductor) or as a result of impurities (extrinsic semiconductor)
2. (Electronics)
a. a device, such as a transistor or integrated circuit, that depends on the properties of such a substance
b. (as modifier): a semiconductor diode.

sem•i•con•duc•tor

(ˈsɛm i kənˌdʌk tər, ˈsɛm aɪ-)

n.
1. a substance, as silicon or germanium, with electrical conductivity intermediate between that of an insulator and a conductor.
2. a basic electronic component incorporating such a substance, used in communications equipment and in computers.

sem·i·con·duc·tor

(sĕm′ē-kən-dŭk′tər)
Any of various solid substances, such as silicon or germanium, that conduct electricity more easily than insulators but less easily than conductors. Semiconductors are able to do this because they have a small number of electrons that have escaped from the bonds between the atoms, leaving open spaces. Both the electrons and the open spaces can carry an electric current.

semiconductor

A substance with properties between those of an electrical insulator and a conductor at room temperature, but with conductivity modified by temperature and impurities; crucial in modern electronic devices.
