Optimisation of the electrical and optical properties of ZnO nanowires for advanced nanodevice applications

Funding: 2009: $115,000

Project Member(s): Phillips, M., Ton-That, C.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2009

Summary: This project aims to devise original methods to fabricate ZnO nanowires with specified dimensions and opto-electronic properties. We will exploit recent advances in scanning electron microscopy to directly study at high magnification nanowires as they grow. Detailed characterisation of individual nanowires will establish precise relationships between their physical properties, dimensions and a broad range of growth conditions. Reproducible growth of ZnO nanowires with prescribed electronic and luminescence properties will enable the development of the next generation of nano-devices, such as high performance solar cells, ultra high sensitivity sensors and ultra high speed-electronics.
