Formation of micro-patterned structures on fluoropolymers including PTFE, FEP and PVDF will be performed using micro-contact printing techniques in combination with surface graft co-polymerisation; an innovative convergence of two emerging technologies. Surface modification and structures formed will be investigated using contact angle measurements and mapping, and surface analytical techniques (XPS and TOFSIMS). Processing methodologies will be identified which allow formation of micrometre scale tracks, and selected area deposition of sensor films and reactive biomaterials. Trial device fabrication will be undertaken using conditions and device structures similar to those required for production of diagnostic sensors and arrays, and polymer-based electronic devices.Read moreRead less
Tuning electronic and optical properties in twisted 2D semiconductors. This project aims to build and characterise a family of novel electronic materials: layers of atomically thin semiconductors stacked with a twist, to realise new electronic phases and new low-energy electronic devices.

This project aims to build and characterise a family of novel electronic materials: layers of atomically thin semiconductors stacked with a twist, to realise new electronic phases and new low-energy electronic devices. The project adopts an interdisciplinary approach combining advanced experimental and theoretical techniques. The expected outcomes will be a detailed understanding of the electronic and optical properties of twisted semiconductor superlattices, such that they can be produced with desired properties on demand. The benefits of the project will be new materials for electronics and optoelectronics applications, new links to international organisations, and training of students and postdocs for careers in nanoelectronics.

Semiconductor quantum wells at the atomic scale. The project will prepare novel semiconductor materials based on layered transition metal dichalcogenides in which electrons are confined in atomically-thin planes. This strong confinement leads to new properties that will be studied in this project, including strong electron-electron interactions, strong electron-defect interactions and atomically-sharp heterostructures. Additionally the novel electronic structure of the dichalcogenides leads to n ....Semiconductor quantum wells at the atomic scale. The project will prepare novel semiconductor materials based on layered transition metal dichalcogenides in which electrons are confined in atomically-thin planes. This strong confinement leads to new properties that will be studied in this project, including strong electron-electron interactions, strong electron-defect interactions and atomically-sharp heterostructures. Additionally the novel electronic structure of the dichalcogenides leads to new electronically and optically addressable information storage and transmission based on the 'valley' of the electrons. It is expected that these new properties will enable photovoltaics, quantum-confined devices operating at room temperature, and new information processing based on the valley degree of freedom.Read moreRead less
On-surface atomic-scale engineering of topological organic nanostructures. The goal of this project is to synthesise and characterise low-dimensional organic nanostructures, in which the atomic-scale morphology and electronic structure give rise to nontrivial topological electronic states. Successful design of organic materials with topological electronic states would pave the way for the development of new technologies in dissipation-less electronics, spintronics and quantum information process ....On-surface atomic-scale engineering of topological organic nanostructures. The goal of this project is to synthesise and characterise low-dimensional organic nanostructures, in which the atomic-scale morphology and electronic structure give rise to nontrivial topological electronic states. Successful design of organic materials with topological electronic states would pave the way for the development of new technologies in dissipation-less electronics, spintronics and quantum information processing, with the flexibility and efficiency that organic compounds can offer. The project plans to exploit metal atoms and organic molecules as building units in approaches of supramolecular chemistry applied on surfaces, to achieve structural and electronic control at the single atom level.Read moreRead less
