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 ...

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

Electrical current flows easily through a conductor, but does not flow through an insulator. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

An insulator will have a large band gap, making it impossible for electrons to circulate by being excited into the conduction band. In contrast, conductors have a band gap of almost zero and so will ...
