The need for indium droplets to initiate self-catalyzed growth of InAs nanowires has been highly debated in the last few years. Here, we report on the use of indium droplets to tune the growth direction of self-catalyzed InAs nanowires. The indium droplets are formed in situ on InAs(Sb) stems. Their position is modified to initiate growth in the <11-2> or equivalent directions. We also show that indium droplets can be used for the fabrication of InSb insertions in InAsSb nanowires. Our results show that indium droplets can be used to determine the initial stages of growth of InAs nanowires as well as provide added flexibility to nanowire growth, enabling the formation of kinks and heterostructures and offering a new pathway towards defect-free crystals.
