ABSTRACT
Nanoarrows, an extremely rare nanostructural type, are fabricated by various methods, such as template-assisted nanoarea selective growth on GaN substrates such as InGaN1,2 (Figure 4.1), metalloorganic CVD (ZnCdSe alloy three-bladed nanoarrowheads, Figure 4.2),3 or use of oxidizing and reducing ambients (In2O3).4 The reducing reagent, ethanol, made the growth environment indium rich, resulting in the growth of indium-£lled In2O3 tubular nanoarrow structures. In2O3 nanoarrows (obtained also by CVD) and other nanoforms have important potential applications as functional blocks in nanodevices.5 ZnO6 nanoarrows were also obtained, among a large series of other structural types.
