| 抄録(英) | We investigate the scanning tunneling microscopy (STM) on the multi-layered cuprate superconductor Ba2Ca4Cu5O10 (O 1-x Fx)2 (F0245, Tc =79 K, x = 0.72).
The STM images show clear atomic lattice structures and large random spot structures. Among the regular square-lattice atomic corrugation with the period of the lattice constant a ~0.38 nm, another kind of atomic spots arranged into the four-fold cross shaped clusters is clearly observed along the diagonal direction with the period of 0.26 nm. These clusters are being distributed inhomogeneously, which are due to the charge imbalance associated with the apical O/F rate. The apical O and F sites are also identified from the positions of such clusters in the STM topographic images. |
