N2 - Nanowire integration into current processing technologies remains an important challenge regarding scalable device fabrication, particularly for metal-catalyzed III-V nanowires integrated with Si-based electronics. Controlling nanowire orientation, either in or out of a substrate plane, by using different metal catalysts may work as a tool to address these issues. Here, we report an extensive investigation of InP nanowires catalyzed by Au, Ag, and AuxAg1-x nanoparticles grown on GaAs substrates with different orientations. Using statistical analysis of the experimental data and modeling, we show that the ratio of the droplet surface density over the In precursor flux is the key parameter controlling the nanowire growth mode and spatial orientation. Overall, these results provide further understanding of the vapor-liquid-solid growth of planar nanowires and allow us to find tools for the control of growth orientation of III-V nanowires catalyzed by different metallic nanoparticles on lattice-mismatched substrates.
