Summary
Atomic Engineering of Molybdenum Disulfide for Ultra-Scaled Electronics. This project aims to explore novel approaches to device fabrication and functionality by atomic-level engineering of next generation electronic materials. As transistors shrink towards the atomic scale, conventional fabrication methods fail and device behaviour is altered by emerging quantum effects. Atomically thin two-dimensional (2D) crystals are emerging as next-generation electronic materials in nanoelectronics.

This project aims to explore novel approaches to device fabrication and functionality by atomic-level engineering of next generation electronic materials. As transistors shrink towards the atomic scale, conventional fabrication methods fail and device behaviour is altered by emerging quantum effects. Atomically thin two-dimensional (2D) crystals are emerging as next-generation electronic materials in nanoelectronics. However, no reliable fabrication techniques currently exist at the targeted sub-10-nanometre scale and basic scientific investigation of the operation of these ultimately small devices is needed. The project plans to use innovative approaches to investigate the physics of atomic-scale electronic devices and explore entirely new device concepts and functionalities for future quantum electronics.Read moreRead less

This project aims to develop the hydrogen-terminated surface of diamond as a new semiconducting platform for carbon-based spintronics. It will build upon recent experimental advances that have shown diamond to possess a two-dimensional (2D) hole-based system with strong spin-orbit coupling. As a semiconductor with unique spin properties, surface conducting diamond offers considerable advantages over other 2D materials such as graphene and topological insulators. These unique properties will be exploited to realise novel semiconductor device architectures for the manipulation of spin using electric fields, and for the study of new spin transport phenomena and quasiparticle excitations at semiconductor-superconductor interfaces.Read moreRead less

This project is anticipated to provide a platform for nanoelectronic devices where quantum degrees of freedom remain robust up to very high temperatures. The one-dimensional edge channels of two-dimensional topological insulators are an emerging research area that challenges our understanding of quantum matter at the atomic scale. The project aims to deliver a new insight into the nature of edge channel transport and scattering by directly measuring their wave functions and quasi-particle excitations with atomic scale resolution. By applying these methods to systems with very large topological gaps, the anticipated results will provide a foundation for robust high-temperature, industry-compatible spintronics. The intended outcomes may improve computational speed in new information technologies and reduce power consumption.Read moreRead less
