The study explores the control of InAs shell growth on GaAs nanowire cores, focusing on selectivity influenced by core crystal phase and morphology.
The research highlights two main findings: crystal phase selective growth occurs under certain conditions, and facet-dependent selectivity can be achieved by altering nanowire morphology.
A novel 2-step growth method is proposed to manage InAs shell thickness while preserving selectivity, enabling enhanced functionalities in one-dimensional nanostructures through precise engineering.
