Moving heat around where you want it to go—adding it to houses and hairdryers, removing it from car engines and refrigerators—is one of the great challenges of engineering.

Topological insulators have notable manifestations of electronic properties. The helicity-dependent photocurrents in such devices are underpinned by spin momentum-locking of surface Dirac electrons that are weak and easily ...
In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum oscillation, is typically observed ...

Topological insulators (TIs) have an insulating interior and support conducting surface states with additional interfacing properties. The exotic metallic states on their surfaces can provide new routes to generate new phases ...
The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons—the subatomic particles that carry electricity—are elementary particles and cannot be split, fractions of electronic ...
