Hexagonal boron nitride for deep ultraviolet device applications. 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, ....Hexagonal boron nitride for deep ultraviolet device applications. 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
Epitaxial growth of III-V microring lasers for integrated silicon photonics. This project aims to investigate the growth and demonstration of compound semiconductor microring lasers on silicon substrates, using selective area growth to engineer the shape of the lasing cavity at the nano/micro-scale.

This project aims to investigate the growth and demonstration of compound semiconductor microring lasers on silicon substrates, using selective area growth to engineer the shape of the lasing cavity at the nano/micro-scale. Silicon photonics is currently a dominant technology in optical and data communication systems, and the continued development demands higher speeds, lower power consumption and lower costs. However, on-chip integrated, high efficiency lasers are still elusive due to mismatch in material platforms between the lasers and silicon substrates. This project will produce reliable, efficient and easily manufacturable laser sources integrated on silicon photonic chips. It is also expected to pave the way for more development of this technology by the industry to further drive the cost of silicon photonics technology down whilst increasing data transmission speed.Read moreRead less
