Summary
Engineering ferroelectric topologies in freestanding membranes. This DECRA proposal is focused on the exploiting controlled motion, annihilation and creation of real space topological defects (polar skyrmions, vortices and merons) in free-standing ferroelectric superlattices. Topological states in ferroic materials arise from spin/dipolar textures (the spins/dipoles can be considered as quasiparticles) which condense to form topological defects. The imposition of precisely controlled elastic bou ....Engineering ferroelectric topologies in freestanding membranes. This DECRA proposal is focused on the exploiting controlled motion, annihilation and creation of real space topological defects (polar skyrmions, vortices and merons) in free-standing ferroelectric superlattices. Topological states in ferroic materials arise from spin/dipolar textures (the spins/dipoles can be considered as quasiparticles) which condense to form topological defects. The imposition of precisely controlled elastic boundary conditions through an applied bending stress, temperature profiles and electric fields to the membranes enables tailored functional responses without any interference from substrate clamping effect. This yields multifunctional materials with enhanced operational speed, sensitivity and energy-efficiencies.Read moreRead less
Porosity in Si, Ge and the Si(x)Ge(1-x) alloys induced by ion irradiation. Ion beam methods will be used to form porous layers in Si, Ge and their alloys with a range of technological applications. The distributions of pore size and shape will be characterised with laboratory and synchrotron-based analytical techniques including a 3D reconstruction of the irradiation-induced porous structure.
Spin manipulation in oxide magnetic semiconductors towards spintronics applications. The project is to develop high quality diluted magnetic semiconductors (DMS) with magnetic element dopant for practical spintronics applications. The properties for the qualified DMS include intrinsic ferromagnetism, effective spin manipulation, high spin polarisation and long distance of spin transport, which have not been well addressed so far. This project will investigate these issues using advance tools, in ....Spin manipulation in oxide magnetic semiconductors towards spintronics applications.

The properties for the qualified DMS include intrinsic ferromagnetism, effective spin manipulation, high spin polarisation and long distance of spin transport, which have not been well addressed so far. This project will investigate these issues using advance tools, including muon spin relaxation and neutron reflectometry.

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.

Summary
Fatigue degradation in lead-free piezoelectric ceramics: the key factor for successful industrial implementation. Many everyday devices, that is mobile phones, operate with lead-based ceramics, which can be hazardous; although there are promising lead-free materials, these show complex electric behaviour which can lead to structural damage and device failure. This project will define the degradation mechanisms so that reliable non-toxic ceramics can be designed.
