团簇组装和纳米结构

8 Cluster Assemblies and Nanostructures

原子团簇、团簇材料、线性多层异质结构、超薄膜等人工合成材料、具有维数低、对称性少、几何特征显著以及一系列奇异的电、磁、光和化学性质。而以它们作为基本结构单元构成具有一定功能的体系,称为纳米结构,是在纳米尺度上材料和器件设计密切结合的新形式。

Atomic clusters,cluster assemblies,Iinear chains,multilayers,heterostructures,ultrathin films,etc.are prepared artificially and characterized by low dimension,reducing symmetry and unique geometry with a number of unusual electric,magnetic,optical and chemical properties.They are used as building units in a turn to synthesize new nanophase materials or nanostructures with certain specific functions.
