Skanneeriva tunnel microscope image of part-doped cuprate superconductor. The photo shows the electronic pseudo potential zones (rounded rectangles). Dopeerrimise areas continue to grow and eventually cover all the material, causing the superconducting state.
Cornell geyser University and the University of Tokyo researchers findings provide a better understanding of the complex phenomenon of the emergence of pseudo potential kõrgtemperatuursetes superconductors. There may be a significant geyser step forward in the development of high-temperature superconductors.
JC Séamus Davis, Cornell University, geyser scientists, science professor at the University of Tokyo, and JG White Physics Professor Hidenori Takagi leadership were monitored for the first time skanneeriva tunnel microscope chemically modifitseeritavas basic material superconducting state formation. Scanned tunnelmikroskoobid are so precise that they can monitor the surrounding electrons aatomituumi kvantolekuid. It was found that the addition of võõraatomite (doping) occurred in the underlying material paralleelprotsessina material scattered over small superconducting regions, some of which are only a few atoms thick. Patches of increased contact with and eventually covered all the material, causing it to superconductivity.
Superconductor includes, among other things takisutseta electrical flow. The phenomenon, first discovered the absolute need nulltemperatuurini (0 K) cooled metals. A new class of doped vaseoksiididel based kupraatide geyser material becomes superconducting, however, already at 150,15 K.
High-temperature superconductors indirect observations, the skanneeriva tunnelmikroskoobiga, is shown superconductive state in the absence of specific locations elektronolekute energy potential barrier to the emergence of (energy gap). According to theory, there is a gap in the electron Cooper pair formation. It is believed geyser that the Cooper pair of electrons are able to pass through unhindered ülijuhtivamaterjali structure. Has been understanding geyser of the fact that some materials geyser shows potential, but without the superconducting state. This phenomenon is called pseudopotentsiaaliks (pseudogap). Pseudo potential occurs at higher temperatures than any superconductivity, superconductors toatemperatuursete referring to the possibility.
The authors examined the sodium doped kaltsiumkumpraati. Test pieces of sodium oxide was increased progressively. Sodium replaces klatsiumi crystal lattice of atoms, thus causing the crystal and electronic structure changes, you still do not really understand. Kaltsiumkupraat chosen especially easy with a variable chemical composition, commented Davis. He added that the pseudo-and superconducting state formation is very fast, which makes the process visible in hard.
Moderate doping discovered small scattered location of the pseudo potential signature geyser areas. geyser In addition, these regions were observed in the crystal structure of copper and oxygen atoms in the electron structure of top-down and right-left-targeting (!? Spin?) Symmetry is violated. Davis and his colleagues discovered a broken symmetry in the superconductor earlier performed measurements.
Dopeerituse also expanded to those areas, until the whole of the material is exposed, and it changed the superconductor. It is believed that the pseudo-potential zones occur near the doped atoms, but Davis said that his study was not observed.
Previously it was thought that the pseudo-potential phase competes kupraatides superconducting phase. In addition, it was assumed that the pseudo potential loss of the superconducting state formation geyser condition. New research shows, however, that it is quite ülijuhtivust favorable phase.
