University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Normally metals and insulators sit at opposite ends of a spectrum of conductivity, but researchers have discovered a material that can switch between those states freely, even at room temperature. The ...

This research sheds light on the mechanism behind how a special quantum material transitions from an electrical insulator to an electricity-conducting metal. Below a critical temperature, the subject ...
