Materials that are neither good conductors nor insulators.
A material commonly based on silicon or germanium with a conductivity midway between that of a good conductor and an insulator. Semiconductors are used to manufacture transistors, which are used to construct logic gates.
Solid crystalline materials whose electrical conductivities are intermediate between that of conductors and insulators, and which are usually strongly temperature-dependent.
Solid materials such as silicon that have a resistivity midway between those of a conductor and a resistor. These materials are used as substrates for semiconductor devices such as transistors, diodes, and integrated circuits.
Go to Materials & Technology Any material that has a limited capacity for conducting an electrical current with properties between those of a conductor (e.g., copper) and an insulator (e.g., rubber).
are materials whose properties fall between those of insulators and conductors, and is also the term used for all electronic components made from semiconductor material. Semiconductors, most commonly silicon and germanium, are the basic foundation of nearly all solid-state electronic devices.
