Ferroelectric piezoelectric materials and key problems associated with their applications in mechanical, electrical and optical energy transformations. This project aims to investigate the dynamic microstructure of ferroelectric piezoelectric materials in response to electrical fields or mechanical stresses, and therefore identify the factors enhancing the mechanical, electrical and optical couplings for intentional improvement and development of these materials for use in energy transformations ....Ferroelectric piezoelectric materials and key problems associated with their applications in mechanical, electrical and optical energy transformations.

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
