由于其著名的22x根3重构，Au(111)表面可以被认为是生长金属团簇纳米结构阵列的理想衬底。在这封信中，我们报道了这种重建与Au(111)表面紧密堆积台阶之间的相互作用的完整研究。扫描隧道显微镜实验清楚地表明，台阶附近的重构行为在很大程度上取决于台阶的微观结构。这一结果对管理新的纳米结构衬底特别感兴趣，根据这两种步骤的相对稳定性进行了解释。
Due to its famous 22x root 3 reconstruction, the Au(lll) surface can he considered as an ideal substrate to grow nanostructured arrays of metallic clusters. In this letter, we report a complete investigation of the interaction between this reconstruction and the close-packed steps of the Au(lll) surface. Scanning tunneling microscopy experiments clearly demonstrate that the behaviour of the reconstruction in the vicinity of steps depends drastically on the step microstructure. This result, of particular interest for the managing of new nanostructured substrates, is interpreted in terms of the relative stability of both types of steps.
