Researchers at The University of Manchester in the UK, led by Dr. Artem Mishchenko, Prof Volodya Fal'ko and Prof Andre Geim, have discovered the quantum Hall effect in bulk graphite—a layered crystal consisting of stacked ...

Surprising electronic disorder in a copper oxide-based ceramic

Cuprates, a class of copper-oxide ceramics that share a common building block of copper and oxygen atoms in a flat square lattice, have been studied for their ability to be superconducting at relatively high temperatures. ...

Superconductors: Resistance is futile

Every standard cable, every wire, every electronic device has some electric resistance. There are, however, superconducting materials with the ability to conduct electrical current with a resistance of exactly zero – at ...
