Self-organized hierarchical ZnS/Si[O.sub.2] nanowires heterostructures

Article Abstract:

Novel hierarchical heterostructures formed by wrapping ZnS nanowires with highly dense Si[O.sub.2] nanowires were synthesized by vapor-liquid-solid process. The study indicated that a typical hierarchical ZnS/Si[O.sub.2] heterostructure consists of a single-crystalline ZnS nanowire (core) with diameter gradually decreasing from several hundred nanometers to 20 nm and adjacent amorphous Si[O.sub.2] nanowires (branches) with diameter of about 20 nm.

Hierarchical saw-like ZnO nanobelt/ZnS nanowire heterostructures induced by polar surfaces

Article Abstract:

The synthesis of saw-like nanostructures composed of ZnO nanobelts and ZnS nanowires by a simple thermal evaporation process is reported. The formation of saw-like heterostructures is induced by the polar surfaces of wurtzite ZnO and ZnS and their photoluminescence properties are studied at room temperature.

Growth of self-organized hierarchical ZnO nanoarchitectures by a simple In/In2S3 controlled thermal evaporation process

Article Abstract:

The controlled growth of novel hierarchical nanoarchitectures is reported, using a simple atmospheric pressure thermal vapor deposition method. In the process, both the morphology and the construction units could be efficiently controlled by a simple adjustment of the weight ratio of In/In2S3.
