The Cooper Pair Electrons Origination in Copper Oxide Superconductors

An unambiguous determination of the pairing electrons origination in copper oxide superconductors in necessary to understanding the origin of high-temperature superconductivity. Several years ago, several experiments have produced strong evidence for d-wave pairing symmetry. This result also rules out different from the symmetry in conventional superconductors. Using quantum chemical bond theory to research into the effect of chemical bonding on the feature of element nature change and its resulting change on the copper oxide superconductivity. The origin of Cooper pair electrons in the copper oxide is studied with the symmetry characteristics of superconducting electrons. A conclusion is obtained that Cooper pairs of high Tc copper oxide originate the no-bonded electrons of the bearing superconducting elements. This is an important notion of a thorough understanding of mechanism of high Tc copper oxide superconducting.
