Towards High-quality Hetero-epitaxial III-V Semiconductor Nanowires. The use of semiconductor nanowires has uncovered many scientific curiosities and extended their potential applications in many fields. In general, nanowire growth is governed by metallic catalysts, involving nanowire nucleation and growth. So far, the role of catalysts during nanowire nucleation is not clear and needs urgent attention.

The use of semiconductor nanowires has uncovered many scientific curiosities and extended their potential applications in many fields. In general, nanowire growth is governed by metallic catalysts, involving nanowire nucleation and growth. So far, the role of catalysts during nanowire nucleation is not clear and needs urgent attention. This project aims to investigate the behaviour of catalysts before and during the nucleation of III-V nanowires by means of nano-characterisation to ultimately integrate high-quality III-V nanowires on silicon substrates. The new knowledge developed from this project is expected to provide critical insights for developing high-quality III-V nanowires integrated on silicon substrates.Read moreRead less

Vapour phase detection of chemical warfare agents. This project aims to create luminescent plastic optoelectronic materials that can detect airborne chemical warfare agents, particularly nerve agents. Such agents are often odourless and invisible at lethal concentrations, so technology must detect and identify them before exposure.

This project plans to investigate the growth of an alternative material, hexagonal boron nitride, for use in high performance deep-ultraviolet (UV) light-emitting diodes (LEDs). Deep-UV LEDs are robust and highly portable devices that replace traditional mercury/deuterium-based UV sources, and have applications in water or air sterilisation, photo-dermal therapy, covert communication and bio-chemical agent identification. However, despite major worldwide effort in the development of aluminium gallium nitride deep-UV LEDs, their efficiency is still extremely low. Understanding the fundamental growth, doping and alloying mechanisms of hexagonal boron nitride will allow us to engineer its properties and create high-efficiency devices.Read moreRead less
