Dopants dramatically alter electronic structure of superconductor

Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously ...

Certain doped-oxide ceramics resist Ohm's Law

For months, Anthony West could hardly believe what he and his colleagues were seeing in the lab -- or the only explanation for the unexpected phenomena that seemed to make sense.

Atoms placed precisely in silicon can act as quantum simulator

In a proof-of-principle experiment, researchers at UNSW Australia have demonstrated that a small group of individual atoms placed very precisely in silicon can act as a quantum simulator, mimicking nature - in this case, ...

Coexistence of superconductivity and magnetism

( -- Scientists from the University of Sydney are celebrating the 100th anniversary of superconductivity with a discovery of their own.

New family of tiny crystals glow bright in LED lights

( —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.

Researchers peer into nanowires to measure dopant properties

( -- Semiconductor nanowires -- tiny wires with a diameter as small as a few billionths of a meter — hold promise for devices of the future, both in technology like light-emitting diodes and in new versions ...
