Growth of Highly Orientated and Well-aligned ZnO Nanowhiskers using Aqueous Solutions Xiulan Hu1,a, Yoshitake Masuda1,b, Tatsuki Ohji1,c and Kazumi Kato1,d 1 National Institute of Advanced Industrial Science and Technology (AIST), 2266-98 Anagahora, Shimoshidami, Moriyama-ku, Nagoya 463-8560, Japan a xiualan-hu@aist.go.jp, b masuda-y@aist.go.jp, ct-ohji@aist.go.jp, d kzm.kato@aist.go.jp Keywords: Nanowhiskers; Growth from solution; Semiconducting materials; ZnO; Morphology Abstract Length-tailored, monodisperse, highly orientated, single-crystalline hexagonal and aligned ZnO nanowhiskers were grown onto F-doped SnO2 conductive glass (FTO) substrate at 88 C using an aqueous solution.
Control of the size, morphology and orientation of ZnO crystallites on the substrates such as nanostructure arrays is thus a prerequisite for the creation of materials having high specific surface area for various fields of industry and high-technology application including photovoltaic and optoelectronic devices[8, 9].
