    Oxygen deficiency in the iron-based HTSCGdFeAsO 1�� seems to create a parallelogram shaped Fe2+-ion/oxygen deficiency pattern in the Fe2O2 plane in c-direction. These two-dimensional nano structures form superconducting current channels which are separated by h = 0.828nm. The doping distance in direct ion of the super-current shows a strong correlation to the transition temperature

    High temperature superconducting with two doping atoms in La-doped Bi-2201 and Y-doped Bi-2212

    These crystals have two doping patterns given by oxygen excess and doping with an additional atom with projected positions in theCuO2 plane. Both doping elements are necessary for the occurrence of superconductivity. Where the two doping patterns overlap, the point matched locations actas there sonating superconducting pathway and might explain a correlation between Tc and the doping structure

    Doping patterns in N-type high temperature superconductors PLCCO and NCCO

    Get PDF
    It has been demonstrated that the correlation between the doping distance and the critical transition temperature Tc for P-type HTSCs also applies to double doped N-type HTSCs. It is suggested that electron doped HTSC s also form superconducting current channels lying parallel in the CuO2 plane
