Novel two-dimensional nanomaterials – so called “Janus” transition metal dichalcogenides (TMDs) - are featured by breaking out-of-plane structural symmetry that enables prolongated exciton lifetime, strong spin-orbit coupling, large vertical piezoelectric polarization, and exceptional electromechanical properties. We plan to develop reliable and efficient synthetic routes for various "Janus" TMDs and their heterostructures, to investigate their physical properties, and find the ways of property tailoring. Deep understanding of structure-property relationships uncovered for these materials will pave the way for transferring discovered new features into cutting-edge technologies in electromechanical, optoelectronic, and catalytic fields.Read moreRead less

Solid state sources of single photons ("quantum emitters") are a key building block for implementation of scalable quantum technologies. Amongst many potential platforms studied, impurities in hexagonal boron nitride (hBN) are at the forefront due to their brightness and ease of manufacturing. However, their main disadvantage is spectral instability which prohibits engineering of practical devices. The current project will address this bottleneck and deliver an optically stable solid state quantum light source in hBN. The project will produce a robust hardware toolkit for quantum technologies. It will provide excellent training for young Australians and generate key intellectual property for quantum startups and the quantum industry.Read moreRead less
