High-Temperature Superconductor Phonon Theory Officially Dead Ever since physicists discovered high-temperature copper oxide superconductors during the 1980s, they have been trying to explain how the phenomenon is experienced from the point of view of their understanding of the basic mechanism involved in low-temperature superconductors, which is determined by pair electrons vi... 24 April 2008 04:04 GMT Electron Repulsion Responsible for Superconductivity Superconductivity was discovered at the beginning of the 20th century, when scientists started experimenting with mercury cooled down to temperatures only 4 degrees above absolute zero. They observed that, during the transition to a superconducting state, materials started to experience electrical resistance close to... 11 April 2008 05:51 GMT Surprise, Superconductors! Superconductivity is a property of materials exhibited through zero electrical resistance while being cooled to temperatures close to absolute zero. However, aside the vast majority of materials that require such low temperatures, there is a series of special materials, mostly ceramics, which experience zero electric... 13 February 2008 03:41 GMT
