水热法制备反蛋白石结构氧化锌微米柱
首发时间:2013-03-06
摘要:本文使用预先设计了生长无孔氧化锌微米柱的工艺,氧化锌单晶在分布有锌源种子的单晶硅基底上进行水热法生长将沿极晶体0001方向生长。通过表征可知在该工艺下生长出2-3微米的氧化锌微米柱是可行的。通过对氧化锌生长机理和不同型核的竞争关系进行研究分析,本文又分别提出了运用了不同锌源浓度水溶液在覆盖不同后的聚苯乙烯微球的光刻胶刻蚀的阵列模板上生长出有序的反蛋白石结构氧化锌微米柱的方法,通过表征分析,证实高浓度锌源水溶液方法对生长出有序孔氧化锌微米柱是具有可行性的。

Hydrothermal process towarlds ZnO microrods with porous structures
Abstract:The single crystalline ZnO(0001) films were grown on Si(111) wafers by hydrothermal process. It is possible to deposit ZnO microrod with 2-3μm in thickness. In this paper, Hydrothermal systhesis with different concentration were employed to fabricate zinc oxide microrods on the colloidal crystal templates covered on the seeded substrate. It is possible to make 3D porous structure with rod shape ZnO structure by using 3D porous structures.
Keywords: Materials Physics and Chemistry ZnO Hydrothermal Three-dimensional template
