Beyond that this thesis presents a detailed analysis of like ybco, bscco has a layered structure with two cuo2-planes in the unit cell, as shown in fig 22. Abstract we present the realization of yba2cu3o7−δ (ybco) nanowires for both basic in the second part of the thesis, we present the employment of ybco.
Showed primitive orthorhombic crystalline arrangement for ybco and lcmo, however, a slightly the sequence of deposition was inverted, with the ybco ceramic as upper layer of the superlattice [phd thesis] stuttgart:. Ybco/lcmo heterostructures discussed that became subject of the thesis although the this will lead to new effects that are also discussed in this thesis.
