我们描述了在单晶表面原子束生长过程中，通过自组装的方式，在吸附原子、分子、半导体量子点和金属岛的有序超晶格的创造方面的最新进展。这些表面通常具有长周期的重构或应变释放模式，用作非均相成核的模板。然而，排斥性吸附物-吸附物相互作用也可以稳定有序的超晶格，埋藏岛生长序列的垂直相关性将在半导体量子点的情况下讨论。我们还提出了新的模板表面，被认为是特别有希望创造新的岛超晶格。
We describe the state-of-the-art in the creation of ordered superlattices of adsorbed atoms, molecules, semiconductor quantum dots, and metallic islands, by means of self-assembly during atomic-beam growth on single crystal surfaces. These surfaces often have long-period reconstructions or strain relief patterns which are used as template for heterogeneous nucleation. However, repulsive adsorbate-adsorbate interactions may also stabilize ordered superlattices, and vertical correlations of growth sequences of buried islands will be discussed in the case of semiconductor quantum dots. We also present new template surfaces considered as particularly promising for the creation of novel island superlattices.
