We studied the mechanism of long range ordering effect in crystallite aggregation in both electrochemical deposition and crystallization from aqueous solution with the help of scanning probe microscopy, field-emission scanning electron icroscopy, micro-X-ray-diffraction from synchrotron radiation and optical in situ observation. The effect of physicochemical environment adjacent to the growing interface on interfacial morphology and growth mechanism is investigated. The process of self-organized growth in our systems and the factors affecting self-organization are studied. 12 papers are published in several important journals, such as Phys. Rev. Lett., J. Phys. Chem., Phys. Rev. E, and J. Phys. Soc. Jpn., etc.. This research is a solid step towards in depth understanding of interfacial growth mechanism, which is essential for control self-organized interfacial growth and for modifying the physical properties of thin films.
