Studies on composite- and assemble-processes of metal and semiconductor clusters and their nanostructures

为了提高团簇图像的分辨率，在透射电子显微镜上安装了一台新型的慢扫描CCD摄像机，并引入了脉冲微等离子体团簇源来制备几种团簇。我们研究了不同金属团簇之间的接触界面特征及其对磁、电和催化性能的影响。我们还观察到了致密的团簇组装膜等优异的磁性能。这些基本结果对于获得高功能的团簇组装材料是非常有用的。

A new slow scan CCD camera was installed in the transmission electron microscope to improve the resolution of cluster images and a pulse micro-plasma cluster source was introduced to prepare several kinds of clusters. We studied characteristics of contact interfaces between different metal clusters and their effects on magnetic, electric, and catalytic properties. We also observed excellent magnetic properties in dense cluster assembled films, etc. These basic results are very useful to obtain highly functional cluster assembled materials.
