Synthesize and Characterize GaN nanowires and nanoparticles for photonic devices

Nanoscale one-dimensional (1D) materials have stimulated great interest due to their importance in basic scientific research and potential technology applications. 1D materials can also be used as building blocks to assemble new generations of nanoscale electronic circuits and photonics. An important issue in the study and application of 1D materials is how to assemble individual atoms into 1D nanostructures in an effective and controllable way. A number of nano lithographic techniques, such as electron-beam lithography and proximal probe patterning, have been developed. These processes, however, generally are slow and the cost is high. Chemical synthesis represents another important approach to 1D structures, it is much more promising in terms of cost and potential for high volume production. A significant challenge of the chemical synthesis is how to rationally control the nanostructures. The aim of this project is to optimize electroless etching processes to synthesize and character
