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 ...

A semiconductor is a material with electrical conductivity between that of a conductor (like copper) and an insulator (like glass). Unlike conductors, which allow electricity to flow freely, and ...

The word semiconductor is comprised of two words, semi (not complete) and conductor (something that can conduct electricity). Electricity is present everywhere, like in home appliances where current ...

The electronic energy states allowed by quantum mechanics determine whether a solid is an insulator or whether it conducts electric current as a metal. Researchers have now theoretically predicted a ...

BUFFALO, N.Y. — Looking only at their subatomic particles, most materials can be placed into one of two categories. Metals — like copper and iron — have free-flowing electrons that allow them to ...

A discovery of how to control and transfer spinning electrons paves the way for novel hybrid devices that could outperform existing semiconductor electronics. Researchers have demonstrated how to ...
