Now, the outside of electric wires are usually covered in plastic because it’s a very poor conductor. It hardly conducts any electricity at all, so we can say it’s an electrical insulator.

Scientists have developed a hybrid material that switches between conducting and insulating states while maintaining ...

Mott insulators can become conductors by changing certain parameters, such as composition, pressure, strain, voltage, or magnetic field. This phenomenon is known as a Mott transition and has promising ...
