Conductors have a band gap close to 0 eV (electronvolts), semiconductors range approximately between 1 and 9 eV, and anything above is usually considered an insulator.

Semiconductors are at the heart of most electronics. We explain what semiconductors are, how they work, and just how tiny those transistors can get.

A rule-breaking, colorful silicone that could conduct electricity. Previously only thought to be insulating, a shift in the ...

Solids can be categorised into conductors, semiconductors or insulators by their ability to conduct electricity. Electron band theory explains differences in conduction. Semiconductors can be ...

A Virginia Commonwealth University (VCU) professor has developed a new, eco-friendly method of producing semiconductor materials.

Semiconductors are unique because their band gap lies somewhere between that of an insulator and a conductor. As a result, semiconducting materials can function ordinarily as insulators, but then ...

Researchers have discovered a material that can switch between an insulator and a conductor freely, even at room temperature. The material, a compound of manganese and sulfide (MnS2), starts off ...
