Summary
Radioisotope-powered Parallel Electron Lithography for High-throughput Nano-manufacturing. This project aims to realise rapid fabrication of controllable nano-devices over large areas with high throughput and low cost. The lack of large-size (greater than four inch) mask and ultra-low dose resist are the fundamental challenges for high-throughput radioisotope-powered parallel electron nano-lithography (RIPEL) systems. This project aims to realise a large-size RIPEL mask by using the ultra-light ....Radioisotope-powered Parallel Electron Lithography for High-throughput Nano-manufacturing. This project aims to realise rapid fabrication of controllable nano-devices over large areas with high throughput and low cost. The lack of large-size (greater than four inch) mask and ultra-low dose resist are the fundamental challenges for high-throughput radioisotope-powered parallel electron nano-lithography (RIPEL) systems. This project aims to realise a large-size RIPEL mask by using the ultra-light supporting material aerographite that has a state-of-the-art ratio value of Young's modulus to cubic density. It will also develop a new inorganic nanoparticle resist with ultra-low dose. These building blocks will enhance RIPEL's throughput by four orders of magnitude. The project will contribute to making processors or solid state storage cheaper and more efficient.Read moreRead less

Rational Design of Novel Multiferroic Materials for Energy Harvesting and Energy Efficiency. Multiferroics are a class of fundamentally complex materials in which several ferroic orders (for example, ferroelectric and ferromagnetic) coexist. The coupling between their electric and magnetic degrees of freedom is controllable via stress and external fields, thus opening the possibility for breakthrough technological developments.

Multiferroics are a class of fundamentally complex materials in which several ferroic orders (for example, ferroelectric and ferromagnetic) coexist. The coupling between their electric and magnetic degrees of freedom is controllable via stress and external fields, thus opening the possibility for breakthrough technological developments. By working at the frontier of complex nanostructured oxide materials, this project aims to establish the rational basis for systematic design of novel artificially layered multiferroics, develop accurate and computationally affordable methods to simulate these materials under finite-temperature conditions, and exploit this knowledge to devise likely revolutionary photovoltaic, nanoelectronic and energy conversion applications.Read moreRead less

Summary
Inks for the fabrication of thin-film photovoltaic devices by solution processable deposition techniques. Due to their high cost the current generation of solar cells has had limited uptake into the market place. With the use of nanoparticle inks that can form light absorbing layers, solar cells may be fabricated cheaply in the future with solution-based manufacturing techniques, such as spray coating or printing.

The project seeks to develop high performance photoferroelectric materials for a wide range of photoenergy conversion technologies like photovoltaics and photocatalytics. For the past 50 years, ferroelectric photovoltaics have only been an academic curiosity due to their low energy conversion efficiency relative to the popular semiconductor photovoltaics. This project aims to unlock the potential of ferroelectric photovoltaics by introducing an ion co-substitution, which is coupled with electron-pinning, into promising ferroelectric materials and investigating the resultant photo-excited electronic and electrical properties. It is anticipated that the outcomes from this proposed project will provide a solution for optimal ferroelectric visible light absorption to achieve high power conversion efficiency in ferroelectric materials for practical photoenergy applications.Read moreRead less
