Electro-mechanics of natural load-bearing materials: understanding mechanisms of toughening, remodelling, and self-healing. Nature provides some of the most advanced functional structural materials, with the capability to remodel and strengthen under changing loads. The origins of the functional properties which allow them to do this will be explored, providing the possibility of developing materials which mimic this behaviour.
'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deli ....'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deliberate introduction of structural and electronic mismatches at an interface. Such purposely induced 'designer defects' in epitaxial oxide thin films will allow new properties to be achieved in nanoscale layers. This is expected to lead to a new class of functional materials to be used in sensors and nanoelectronics.Read moreRead less

This project aims to explore strategies to optimise the magnetisation and Curie temperature by incorporating dopants via ion implantation, and exploiting proximity effects in heterostructures with magnetic thin films. The recently discovered magnetism in topological insulators opens up a new class of materials with potential applications in energy-efficient electronics, data storage and information processing. The central challenges are to control the underlying magnetic structure and stabilise magnetic order at desirable temperatures. The project expects to discover new composite materials and advance our knowledge for designing magnetic components in the next generation of electronics with ultra-low power dissipation.Read moreRead less

This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale. Traditional electromechanical devices based on ferroelectric materials including position sensors, mechanical actuators, and ultrasonic transducers rely on bulk form. As technology moves toward integrated functionalities, future electro-mechanical materials need to be scaled down to thin film form. Currently, doing this induces mechanical constraints that dramatically suppress the electromechanical response. Using this approach one layer relieves this mechanical constraint while the other gives a giant electromechanical response, providing a pathway for future functional devices. Read moreRead less
