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.

The candidate pool for engineered materials that can help enable tomorrow's cutting-edge optical technologies—such as lasers, detectors and imaging devices—is much deeper than previously believed.

Topological insulators have emerged as a major topic of condensed matter physics research, with several novel applications proposed. Although there are now a number of established experimental ...
