Two dimensional cluster lattices on graphene moires on dense packed metal surfaces

在Ir(111)/石墨烯上可以生长出多种材料的超晶格团簇，具有高度的完美性和宏观延展性。这些支持，密集的簇阵列由外延簇组成，具有可调的平均尺寸的窄分布和相当大的热稳定性，基于惰性，无缺陷的衬底。这些特性是独一无二的，本项目的目标是开发这种基于石墨烯莫尔纹的团簇超晶格的科学潜力，旨在进一步发展对团簇超晶格的结合、结构和形成的原子性理解，并研究团簇扩散、团簇动力学、团簇异构体转化以及团簇之间的相互作用。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到矩阵中来创建新型簇材料。最后，我们将利用独特的超晶格性质，并研究所选材料的这种簇阵列的催化、磁性和电子性质。

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.
