Quasiparticles

Scientists have found that a “superatomic” material is the fastest and most efficient semiconductor ever. Taking advantage of a tortoise-and-hare mechanism, the new material can transport energy much faster than silicon.

Ohio State researchers have shown how a common ceramic material can change its thermal conductivity in response to an electrical field, opening the door to solid-state heat switches that could make thermoelectric generators much more efficient.

Exciting times are ahead in the high-tech industries with the discovery by three independent groups that a new class of materials mimic the special electronic properties of graphene in 3D.
