Cluster superlattice membranes consist of a two-dimensional hexagonal lattice of similar-sized nanoclusters sandwiched between single-crystal graphene and an amorphous carbon matrix. The fabrication process involves three main steps, the templated self-organization of a metal cluster superlattice on epitaxial graphene on Ir(111), conformal embedding in an amorphous carbon matrix, and subsequent lift-off from the Ir(111) substrate. The mechanical stability provided by the carbon-graphene matrix makes the membrane stable as a free-standing material and enables transfer to other substrates. The fabrication procedure can be applied to a wide variety of cluster materials and cluster sizes from the single-atom limit to clusters of a few hundred atoms, as well as other two-dimensional layer/host matrix combinations. The versatility of the membrane composition, its mechanical stability, and the simplicity of the transfer procedure make cluster superlattice membranes a promising material in catalysis, magnetism, energy conversion, and optoelectronics.

簇超晶格膜。

簇状超晶格膜由夹在单晶石墨烯和无定形碳基质之间的尺寸相似的纳米簇的二维六角形晶格组成。该制造过程涉及三个主要步骤，即Ir（111）上外延石墨烯上的金属簇超晶格的模板化自组织，共形嵌入无定形碳基质中以及随后从Ir（111）衬底上剥离。碳-石墨烯基质提供的机械稳定性使该膜作为独立材料稳定，并能够转移到其他基材上。从单原子极限到几百个原子的簇，以及其他二维层/主体矩阵的组合，制造程序可应用于各种各样的簇材料和簇尺寸。
