摘要：

We review the topographic and spectroscopic results we have obtained on cold-cleaved YBa2Cu3O7-x single crystals using a low temperature scanning tunneling microscope. The most important feature is the observation of CuO chains on the surface which show modulations with a periodicity of about three times the unit cell.
