On the Ir(111)/graphene moiré cluster superlattices of a large variety of materials may be grown with high perfection and macroscopic extension. These supported, dense cluster arrays consist of epitaxial clusters with a narrow distribution of a tunable average size and considerable thermal stability resting on an inert, defect free substrate. These properties are unique and it is the goal of the present project to exploit the scientific potential of such graphene moiré based cluster superlattices It is intended to further develop the atomistic understanding of binding, structure, and formation of cluster superlattices and to investigate cluster diffusion, cluster dynamics, cluster isomer transformations as well as cluster-cluster interactions. We will explore new, simpler methods of cluster superlattice fabrication and create new types of cluster materials by embedding cluster arrays into a matrix. Finally, we will make use of the unique superlattice properties and investigate for selected materials the catalytic, magnetic, and electronic properties of such cluster arrays.

在Ir（111）/石墨烯莫尔簇超晶格上，可以生长具有高度完整性和宏观延伸的各种材料的超晶格。这些支持的，密集的集群阵列由外延集群与一个可调的平均尺寸和相当大的热稳定性的惰性，无缺陷的基板上休息的窄分布。这些性质是独特的，这是本项目的目标，以利用这种石墨烯莫尔的簇超晶格的科学潜力，它旨在进一步发展原子的理解的绑定，结构和形成的簇超晶格，并调查集群扩散，集群动力学，集群异构体转换以及集群之间的相互作用。我们将探索新的，更简单的簇超晶格制造方法，并通过将簇阵列嵌入矩阵来创建新型簇材料。最后，我们将利用独特的超晶格性质，并调查选定的材料的催化，磁性和电子性质的簇阵列。
