Here, we present the direct real-space cross-sectional scanning tunneling microscopy (XSTM) imaging with atomic resolution to characterize the atomically resolved electronic structure along the c [001] direction in high-temperature superconductive YBa2Cu3O6.81 cuprates. We demonstrate that CO occurs on CuO plane and chain layers with an antiphase correlation along the c-axis direction governed by Coulomb repulsion rather than Josephson tunneling. Similarly, superconductive coherence is also observed in chain and plane layers in YBa2Cu3O6.81. In addition, at the CO phase boundary, the mutually competing behavior between CO and SC phases and a proximity-like boundary region are observed.
The present atomically-resolved XSTM provides a detailed insight into the unexplored interlayer coupling and its spatial interplay with superconductivity and therefore offers a new approach to unravel the fundamental physical mechanisms of superconductivity in cuprates.[1]
