Ordered mono- and double-layer structures of silver nanoparticles on smooth silver substrates are fabricated by self-assembly technique, where 1,4-benzenedithio] (1,4-BDT) and p-aminothiophenol (PATP) are used as the coupling molecules, respectively.

• 利用自组装方法，分别以1，4-二巯基苯(1,4-BDT)和对巯基苯胺(PATP)为耦联分子，在光滑银基底表面上构筑了银纳米粒子的单层和双层有序结构。
