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）的机制以及Ecale层的特征，PD在AU（111）或AU（100）电极上的电沉积之后是电化学瞬态方法和第二个谐波生成。2。 CDTE是通过光助理 - 遗传沉积物在SI（111）上均延伸的3。通过原位原子力显微镜监测金属（如AU，PT和PD）的电化学生长。4。通过生长C和S交替生长CD的ecale。然后，通过在氧气保存水中的极化光照射将其溶解以形成条纹结构。5。通过将AU或ITO底物浸入含有甲基SAM，用甲基，羧酸盐或Ferrocen末端组保护的溶液中，并交替地构建了电动金纳米群的多层。同样，构建了由反向麦克塞尔技术制备的CDS纳米群体的多层。在这两种情况下，多层中的所有纳米簇均具有电活性。6。实现了多核金属复合物的电化学分子外延。
