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 ...

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 ...

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 ...

The use of semiconductor integrated circuits is widespread in devices like radios, televisions, and thermometers. A diode, for instance, is a gadget built of an integrated semiconductor circuit. A ...
