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.

Roller coaster superconductivity discovered

Superconductors are more than 150 times more efficient at carrying electricity than copper wires. However, to attain the superconducting state, these materials have to be cooled below an extremely low, so-called transition ...

Scientists Create Nano-Patterned Superconducting Thin Films

(PhysOrg.com) -- A team of scientists from Bar-Ilan University, Israel, and the Brookhaven National Laboratory has fabricated thin films patterned with large arrays of nanowires and loops that are superconducting -- able ...

NIST Detector Counts Photons With 99 Percent Efficiency

(PhysOrg.com) -- Scientists at the National Institute of Standards and Technology have developed the world's most efficient single photon detector, which is able to count individual particles of light traveling through fiber ...

Gallium nitride transistor could replace silicon

(PhysOrg.com) -- A Cornell researcher has created an extremely efficient transistor made from gallium nitride, which may soon replace silicon as king of semiconductors for power applications.

Physicists discover surprising variation in superconductors

(PhysOrg.com) -- MIT physicists have discovered that several high-temperature superconductors display patchwork quilt-like variations at the atomic scale, a surprising finding that could help scientists understand a new class ...
