Subcategories

• Semiconductor materials - materials that have an intermediate electrical conductivity between a conductor and an insulator
• Superconducting devices - devices that allow zero or almost zero electrical resistance, often operated at very low temperatures and with materials such as mercury
• Superconducting integrated circuits - integrated circuits or ICs that have superconducting properties
• Superconducting magnetic energy storage - or SMES, a system that stores energy in a magnetic field created by the flow of direct current through a superconducting coil cooled below its critical temperatures
• Superconducting materials - materials, which, below a critical temperature, have zero or almost zero electrical resistance
• Superconducting transition temperature - the temperature at which a particular material becomes a superconductor with no electrical resistance
• Wire - a single usually flexible strand of metal that transmits electricity and electromagnetic signals
