| Research Abstract |
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.
