摘要：

We have used a scanning tunneling microscope to investigate the electronic state of CuO chains in YBa2Cu3O7-delta. The observed one-dimensional charge modulations form the nanoscale coherent domains, exhibiting an existence of the interchain correlations. For Zn-substituted crystal, the influence of the local destruction of planar superconductivity is not seen. These results are explained in terms of the very short-range charge-density waves formed in a monolayer with the atomic vacancies.
