功能纳米模板使分子的自组装成为可能。这种模板的一个特殊类别是sp2杂化单层六方氮化硼或碳(石墨烯)在金属支架上。如果衬底和单层晶格不匹配,就会形成超结构。在铑或钌等底物上,这些超结构具有晶格常数为~ 3nm的单位胞。它们是波纹状的,含有亚单位,其行为就像分子或量子点的陷阱,它们足够小,可以在室温下运行。对于Rh(111)上的石墨烯,我们强调了波纹景观中小山丘的新结构元素。对于像水这样的分子,研究表明新的相在这样的模板上聚集,它们可以被用作“纳米实验室”,在那里并行研究许多单独的过程。此外,研究表明,h-BN/Rh(111)纳米网在3nm单位胞内显示出强烈的扫描隧道显微镜诱导的发光对比,这是一种解决被捕获分子和/或量子点的方法。
Functional nano-templates enable self-assembly of otherwise impossible arrangements of molecules. A particular class of such templates is that of sp2 hybridized single layers of hexagonal boron nitride or carbon (graphene) on metal supports. If the substrate and the single layer have a lattice mismatch, superstructures are formed. On substrates like rhodium or ruthenium these superstructures have unit cells with ∼3-nm lattice constant. They are corrugated and contain sub-units, which behave like traps for molecules or quantum dots, which are small enough to become operational at room temperature. For graphene on Rh(111) we emphasize a new structural element of small extra hills within the corrugation landscape. For the case of molecules like water it is shown that new phases assemble on such templates, and that they can be used as “nano-laboratories” where many individual processes are studied in parallel. Furthermore, it is shown that the h-BN/Rh(111) nanomesh displays a strong scanning tunneling microscopy-induced luminescence contrast within the 3 nm unit cell which is a way to address trapped molecules and/or quantum dots.
