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 ...

In a carefully controlled environment, physicists have managed to stabilize a rare and previously short-lived phase of matter by using a simple method of rapid heating and cooling. This breakthrough ...

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 ...

With an electrical conductivity somewhere in between that of conductors and insulators, semiconductors have become an indispensable part of modern electronics. Nearly all electronics currently use ...

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 ...

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 ...
