| Abstract: | The morphological evolution of GaN nanostructures grown by catalyst-free chemical vapor deposition process was examined.GaN nanowires were synthesized and their morphologies could be tuned by adjusting the growth parameters including substrates,flow of NH3,and growth duration.The crystalline structure and morphology of as-grown products were characterized by X-ray diffraction and scanning electron microscopy.The optimum synthetic parameters of GaN nanowires were obtained in the experiments. |
