Asymmetric Electron Behavior Discovered in High-temperature Superconductors

Back to article | Note about images

Graphic simulation of electron cloud in layer of copper oxide in a cuprate superconductor.

Superconductors conduct electricity without any energy loss and could be ideal for many energy-related applications. Unfortunately, even 'high-temperature' superconductors require very cold temperatures, which limits their use. However these high-temperature superconductors do enter a mysterious, nearly-superconducting state called the 'pseudogap phase' close to room temperature. Researchers at Cornell University have revealed for the first time a directionality in the arrangement of electrons in this state
