Dislocation motion and anelastic recovery in layered ceramic titanate. This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation. Layered sodium titanate is used in energy storage and water treatment, but in-situ tensile tests have observed unconventional deformation behaviour, with significant dislocation motion and anelastic recovery. This project will study the deformation mechanism in layered sodium titanate nan ....Dislocation motion and anelastic recovery in layered ceramic titanate. This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation. Layered sodium titanate is used in energy storage and water treatment, but in-situ tensile tests have observed unconventional deformation behaviour, with significant dislocation motion and anelastic recovery. This project will study the deformation mechanism in layered sodium titanate nanowires through molecular dynamics simulations, empirical interatomic potential, and in situ TEM experiments. Expected outcomes include knowledge of the deformation mechanism of this layered titanate which can be broadened to technologically important layered ceramic materials.Read moreRead less

Giant piezo responses in rare-earth doped eco-friendly relaxor perovskites. This project aims to design and fabricate superior eco-friendly substitutions for lead-based perovskites widely used in piezoelectric devices, to address the long-standing toxic concern of lead for human beings and the environment in the community.

This project aims to design and fabricate superior eco-friendly substitutions for lead-based perovskites widely used in piezoelectric devices, to address the long-standing toxic concern of lead for human beings and the environment in the community. It is expected to surmount the fundamental limit of current approaches to reach giant room-temperature piezoelectric responses in lead-free perovskites through using a pioneering route named rare-earth doped relaxor/morphotropic phase boundary crossover. Success of this project will not only meet the Australia’s ecological sustainability goals, but also provide commercial opportunities for Australia in the large market of piezoelectric devices (> 25 Billion USD annually).Read moreRead less

Transistors are the fundamental building blocks of modern electronic devices, which continue to diminish in size to achieve higher speeds. However, the development of this technology has been impeded by low carrier density in the gate dielectric materials. Therefore, increasing the attainable carrier density has become critically important for both scientific research and industrial applications.

This project aims to develop a material with ultrahigh electron mobility and conductivity well above today’s materials at room temperature to enable next generation nanoelectronics. The demand for higher performance and lower power consumption in electronic systems drives the creation of materials for devices in nanometre scale. The success of these materials depends on enhancement in carrier mobility and conductivity. This project will spatially separate the electron generation layer from the conduction layer by individually engineering the atomically sharp complex oxide heterointerfaces to enhance the electron mobility and density. This is expected to develop new materials and nanoelectronic technologies.Read moreRead less
