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 ...

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 ...

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 ...

A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...

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 ...

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 ...
