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.

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 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

In the past seven years there has been an explosion of interest in materials such as graphene and topological insulators due to their unique electronic properties, culminating in the award of the 2010 Nobel Prize in Physics. However these materials face significant challenges that limit how we can manipulate them and use them in industry. This project will overcome these challenges by developing artificial graphene and topological insulators made using existing nanofabrication techniques on conventional semiconductors already used by industry. This will make it possible to study the unique electronic properties of these materials with unprecedented control, with the ultimate aim of using artificially designed electronic materials in industry.Read moreRead less
