superconductor - noun: superconductor; plural noun: superconductors  a substance capable of becoming superconducting at sufficiently low temperatures.  a substance in the superconducting state.  "as they are cooled through a critical temperature, they suddenly become superconductors"

insulator- noun: insulator; plural noun: insulators

a substance which does not readily allow the passage of heat or sound.  "cotton is a poor insulator"  a substance or device which does not readily conduct electricity.  a block of material, typically glass or ceramic, enclosing a wire carrying an electric current where it crosses a support.

conductor- noun: conductor; plural noun: conductors  1.  a person who directs the performance of an orchestra or choir.  "he was appointed principal conductor of the Berlin Philharmonic Orchestra"  2.  BRITISH  a person in charge of a train, streetcar, or other public conveyance, who collects fares and sells tickets.  3.  PHYSICS  a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.  "graphite is a reasonably good conductor of electricity"  another term for lightning rod.

semiconductor- noun: semiconductor; plural noun: semiconductors  a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.

These are the definitions off of google. Bye :)

superconductor  a material that conducts electricity, but not as well as a conductor

insulator  a material through which little electric current moves

conductor  a material through which electric current flows easily

semiconductor a material that has zero resistance at a very low temperature
