Probing topological edge channels at the atomic scale. 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.

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

Punching holes in GaAs: a novel route to making artificial graphene and topological insulators. 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.

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

We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the depletion of background spins in natural silicon and now aim to push the enrichment to greater extremes. We will integrate the extreme material into functional devices that use electrically detected electron spin resonance to probe exceptionally durable quantum states and open a near-term pathway to large-scale devices.Read moreRead less
