Abstract
Three kinds of ZnO microstructures are controlled synthesized on silicon substrates including microcolumns, microfences and hollow microcolumns. The morphological evolution of the prepared ZnO microstructures are systematically analyzed. It is found that the growth parameters play crucial roles on it, such as the growth temperature and the concentration of gaseous source atoms on the growth surface. Moreover, the optical characterizations suggest the structural advantages of ZnO microfence, that is, its excitation density has been enhanced due to its special symmetric hexagonal array, which has also switched on the p-band emission.
期刊介绍：
The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
