1. To clarify the mechanism of electrochemical atomic layer epitaxy (ECACE) and the characteristics of the ECALE layer, electrodeposition of Pd on Au(111) or Au(100) electrode was followed by electrochemical transient method and second harmonic generation.2. CdTe was epitaxially grown on Si(111) by photoassisted-electrodeposition.3. Electrochemical growths of metals such as Au, Pt and Pd, were monitored by in situ atomic force microscopy.4. ECALE of CdS was achieved by growing Cd and S alternately. It was then dissolved by irradiation of polarized light in oxygen-safurated water to form a stripe structure.5. By dipping Au or ITO substrate into solutions containing Gold nanoclusters protected by thiol SAMs with methyl, carboxylate, or ferrocen terminal group, and polelectrolytes alternately, multi-layers of electroactive gold nanoclusters were constructed. Similarly, multi-layers of CdS nanoclusters prepared by reversed-micelle technique were constructed. In both cases, all nanoclusters in the multilayers were electroactive.6. Electrochemical molecular epitaxy of multi-nuclear metal complex was achieved.

1.为了阐明电化学原子层外延（ECACE）的机理和ECALE层的特性，采用电化学瞬态法和二次谐波法对Pd在Au（111）或Au（100）电极上的电沉积过程进行了跟踪研究.采用光辅助电沉积法在Si（111）衬底上外延生长了CdTe薄膜。利用原子力显微镜原位监测了Au、Pt和Pd等金属的电化学生长. CdS的ECALE是通过Cd和S交替生长实现的。然后用偏振光照射溶解在含氧的水中，形成条状结构.通过将Au或ITO基底交替浸渍到含有由具有甲基、羧酸酯或二茂铁端基的硫醇自组装膜保护的金纳米团簇和聚电解质的溶液中，构建了多层电活性金纳米团簇。同样，通过反胶束技术制备了多层CdS纳米团簇。在这两种情况下，多层膜中的所有纳米团簇都是电活性的。实现了多核金属配合物的电化学分子外延。
