Morphology And Crystallinity Control Of Wet Chemically Grown Zno Nanorods, Janos Volk, Róbert Erdélyi

Turkish Journal of Physics

The controlled growth of ZnO nanorods on technologically relevant substrates is essential for their practical integration into next generation optoelectronic and piezoelectric devices. In this report, highly ordered and uniform vertical ZnO nanorod arrays were synthesized using a facile, low temperature selective area wet chemical growth process. The nanorods were grown through nucleation windows that were patterned in a PMMA mask using electron beam lithography. At first, the technique was demonstrated on `ideal' ZnO single crystal substrates, where the geometrical parameters of the highly uniform and crystallographically coherent nanorods were dictated by the nucleation pattern, the polarity of the substrate, …
