Growth mechanisms of one-dimensional zinc oxide hierarchical structures

摘要

One-dimensional (ID) zinc oxide (ZnO) hierarchical structures have been self-assembled on amorphous carbons using thermal chemical vapour transport and condensation. Three typical micro- and nanostructures consisting of micrometre-sized rods and nanometre-sized needles were observed. Growth mechanisms were established to elucidate the growth properties of ID ZnO hierarchical structures.
