从扫描隧道显微镜、表面x射线- din反应实验和理论预测之间的相互作用中，导出了一个明确的Cu(110)-c(6x2)O表面重构的结构模型，其中10个Cu原子在c（6x2）单元格内，其中两个形成Cu上层结构。总的情况是，目前的重构以及Cu(110)-(2x1)O和Cu(100)(242& J2)R45 0重构是由Cu-0-Cu链沿[001]方向稳定的。c（6x2）结构的成核和生长优先发生在台阶上。
From an interplay between scanning tunneling microscopy, surface x-ray-diN'raction experiments, and theoretical predictions, an unequivocal structural model for the Cu(110)-c(6x2)O surface reconstruction is derived with ten Cu atoms within the c(6x2) unit cell, two of which form a Cu superstructure A general picture evolves in which the present as well as the Cu(110)-(2x 1)O and the Cu(100)(242& J2)R45 0 reconstructions are stabilized by Cu-0-Cu chains directed along the [001] direction. The nucleation and growth of the c(6x 2) structure occur preferentially at steps.
