Understanding the role of catalysts in the growth of epitaxial semiconductor nanowires and their hierarchical heterostructures (2010-2014)
Abstract
Epitaxial semiconductor nanowires have been a global research focus as key building blocks for future nanodevices. Although various nanowires and their heterostructures have been successfully fabricated, their growth mechanism(s) remain unclear. In general, nanowire growth is mediated by metallic catalysts, which can significantly complicate the growth process. This Fellowship aims, through detailed nanocharacterisations of carefully chosen nanowires with their catalysts, to understand this catalytic role. This project will be first of its kind in this exciting research field. The new knowledge developed from this project will have a significant impact on the future design and manufacture of practically useful nanowire-based devices.
