在振荡电沉积过程中自发形成了垂直于基底的极其有序的锡晶格。各种过程的配合，例如通过自催化晶体生长形成针状体、在反应限制条件下形成长方体以及最密堆积表面的自催化氧化，使得晶格结构能够自组织。该机理通常适用于其他金属的沉积，例如 Zn、Pb 和 Cu。目前的工作为在固体表面形成高度有序的 3D 微米或纳米结构开辟了一个有前途的、独特的领域。
Strikingly well-ordered Sn latticeworks, standing perpendicular to the substrate, are formed spontaneously in oscillatory electrodeposition. Cooperation of various processes, such as needle formation by autocatalytic crystal growth, cuboid formation under a reaction-limited condition, and autocatalytic oxidation at closest-packed surfaces, enabled the self-organization of the latticeworks. The mechanism is generally applicable to deposition of other metals such as Zn, Pb, and Cu. The present work has opened a promising, unique field toward the formation of highly ordered 3-D micro- or nanostructures at solid surfaces.
