This project has two main objectives related to the synthesis of type III-V semiconductor nanowires by the Vapor-Liquid-Solid method. These objectives will expand our understanding of the physical processes involved in the growth of these nanomaterials, as well as point out alternatives to new sensor fabrication methodologies. We intend to explore the control of directionality in planar nanowires, using surface modification processes, which can lead to a better control in the fabrication of sensor devices studied in our group. On the other hand, we will also explore new metallic nanowire catalysts to replace gold, allowing better compatibility with Si technology. The introduction of new catalysts can provide new functionalities in terms of the optical and electrical properties of the nanowires obtained, which should also be studied in this project. With this project, we also expect to increase the number of tools available for studies of biosystems currently developed in the Laboratory of Nano and Biosystems. (AU)
