Insulator vs. Semiconductor

Insulatornoun

A substance that does not transmit heat (thermal insulator), sound (acoustic insulator) or electricity (electrical insulator).

Insulatornoun

A non-conductive structure, coating or device that does not transmit sound, heat or electricity (see image)

Insulatornoun

A person who installs insulation.

Insulatornoun

One who, or that which, insulates.

Insulatornoun

A substance or object that insulates; a nonconductor; as, polyurethane foam is a popular thermal insulator.

Insulatornoun

a material such as glass or porcelain with negligible electrical or thermal conductivity

Semiconductornoun

(physics) A substance with electrical properties intermediate between a good conductor and a good insulator.

Semiconductornoun

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

Semiconductornoun

a conductor made with semiconducting material

Semiconductor

A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way.
