摘要：
Low-temperature scanning tunneling microscopy on the BaO layer of cold-cleaved YBa2(Cu1-xZnx)(3)O7-delta single crystals reveals the one-dimensional charge modulations at lower bias voltage. These charge modulations have various lengths and are distributed randomly in space. The spatially inhomogeneous electronic state is regarded to be induced by Zn impurities in the CuO2 plane just under the BaO layer, because there are no charge modulations on Zn-free samples. The one-dimensional character possibly reflects the interaction between the CuO2 and the CuO-chain layers. (C) 2003 Elsevier Science B.V. All rights reserved.
